FLASHLIGHT SWITCH
Wesley J. Officer, Hampden, and Orville T. Wood,
Clinton, Mass., assignors to Blake Manufactur
ing Corporation, Clinton, Mass., a corporation
of Massachusetts
Application January 29, 1935, Serial No. 3,934
14 Claims. (Cl. 200--60)
Our invention relates to improvements in
flashlight switches, and particularly to that type
of ilashlight switch commonly known in the art
as a three position, locking, slide switch. The
three positions inferred are anl open circuit posi
tion, an intermittent, or flash light position in
which the circuit is closed by intermittent pres
sure on some part of the switch, and a closed
circuit position.
1o
An obj ect of this invention is to provide a three
position, locking, slide switch of sturdy, simple,
economical construction, and having means for
positively locking the switch mechanism in open
circuit position in such a manner that a positive
15 mechanical operation will be required to move the
switch mechanism from this position.
>
A second object of this invention is to provide,
in a switch of this character, a slide member
adapted to automatically assimilate, or compen
20 sate for, all variations in dimensions Which nor
mally occur in the manufacture and assembly of
the switch parts. These variations are the result
of unavoidable conditions, including commercial
tolerances of the thickness of material used,
25 variations in the tools employed due to wear, set
ups, etc., differences in “touch” or “feel” of op
erators with manually operable tools, and varia
tions caused by normal assembling operations.
These normal variations experienced in the as
30 sembly of the several parts of a switch mechanism
'may cause inefficient operation, unsatisfactory
results, and rejections in manufacture and in
spection, and involve a manufacturing expense
in repair and reassembling work. As stated
above,
it is an object of this invention to provide
35
means for automatically compensating for these
variations, resulting in a uniform operation of
all switches, and eliminating the handicaps pre
sented by these variations in dimensions.
40
A third object of this invention is to provide
a three position, locking, slide switch in which
the movable members will snap from one position
to another with a positive, clearly defined “feel”,
These, and other objects and advantages of our
invention, will be more completely disclosed and
described in the following specification, the ac
companying drawings, and the appended claims.
In carrying our invention into effect, we pro
vide in combination with a flashlight tube, or
casing and a switch lead, a housing member, a
slide within the housing having a top member
and a bottom member independently movable
relative to each other vertically, but movable 10
longitudinally only as a unit, a helical compres
sion spring between the top and bottom members
of the slide normally exerting a force to spread
said members apart, a button on the top member
of said slide, electrical contact means on the 15
switch lead and projecting into the housing, open
circuit, flash, and closed circuit positions within
said housing, cooperative means between the
slide and said positions, and means for positively
locking the slide in the open circuit station from 20
whence the slide may be moved only by a posi
tive mechanical operation, whereby the slide,
when engaged in the ñash position may be con
nected with the contact means by pressure on
the button, and when in the closed circuit posi 25
tion, will be in engagement with the contact
means, without pressure on the button.
O-ur invention is clearly illustrated in the ac
companying drawings, in which:---

typical switch slide.
Fig. 2 is a cross, sectional view on the line 2-2

The principal object of our invention is in the
45
flash light switches. The advantage of a helical
spring is that it never loses its spring effect,
which is not true of a flat, or leaf spring. A flat
spring is subject to a permanent “set”, and will
not remain alive, as a helical spring does at all
times. In other words, the coil spring possesses
permanency and long life, while a flat spring does
55 not.

o: Ul
Referring now to the drawings in detail, in
which like numerals refer to like parts through
outr-The switch slide, illustrated in Figs. 1 and 2, is
adaptable for use in any of the switch construc
tions shown in Figs. 3 to 26, inclusive. The slide
slide l has four parts; a top member 2, a bot
tom member 3, a push button 4, and a helical,
expansible spring 5. The button 4 is formed
with corrugations 6 to provide a gripping sur
face for the thumb, or ñnger, of an operator,
and is rixedly secured on the top member 2 by
tabs i, which project through slots 8 and are
bent away from one another to engage the under
side ci the top portion 9 of the top member 2.
The top member 2 is formed with the top por
tion- â, end portions I 0 and inwardly projecting
flanges Ii and II’. A locking slot I2 is formed
at the rear of the top portion 9. The bottom
member 3 is formed with a bottom portion I3,
end walls I4, and outwardly extending flanges
The helical spring 5 tends to force the mem
ber 2 and the member 3 apart, and this move
ment is limited by engagement of the flanges II
with rlanges i I' and I5, as illustrated in Fig. l.
Engagement of ends I6 of the flanges I5 with
60 the ends EG of the member 2 prevents longitudinal
movement of the member 2, relative to the mem
ber 3; but clearance between the flanges I5 and
the top portion 9 of the member 2, permits ver
tical movement of the member 2, relative to the
member 3, and vice versa.
Figs. 3 to 7, inclusive, illustrate a. single con
tact switch construction in which the slide -I is
incorporated. A casing portion IT is formed with
a flat surface, or area I8, over which is secured
a housing member I9. The slide I is slidably
confined within the housing I9, on the ilat sur
face i8. The tube I'I is formed with three posi
tien, or station grooves, or recesses, an open cir
cuit groove 29, a flash groove 2l, and a closed
circuit groove 22.
A conforming ridge, or pro
jection 23, formed in the bottom I3 of the bot
tom member 3 of the slide I is engaged in one
of these station grooves, whenever the slide is at
rest, depending upon the will of the operator.
A switch lead strip 24 is secured on a strip 25
of insulation by means of a contact rivet, or eye
let 26, which projects through an enlarged open
ing 2l in the casing portion I‘I and into the
housing i9. The insulation strip 25 is secured on
the inner surface of the casing portion IT by 10
eyelets
The switch lead 24 is electrically
connected, in the usual manner, to a lamp 29
and the lamp 29 to a battery, or batteries 30, and
the battery 33 is grounded on the easing portion
I?, as indicated in Fig. 3. A downwardly pro
jecting locking lug 3|, carried with or formed in
the housing I9, projects through the locking slot
or recess l2 in the slide I and engages the end
wall Il), when the projection, or ridge 23, is en
gaged in the open circuit groove 2D, to prevent 20
any accidental movement of the slide I from an
open circuit position.
In operation, the switch slide I rests normally
in the position indicated in Fig. 3, with the ridge
23 engaged in the open circuit groove 20, and the 25
slide locked in this position by enga-gement of
the lug 3i in the slot I2. A downward pressure
on the button 4 will depress the top member 2,
thus freeing it from engagement with the lug 3|.
With the member 2 in this depressed position, a 30
forward pressure on the button 4 will force the
slide I forward, relatively speaking, causing the
ridge 23 to ride out of the groove 20, and raising
the bottom member 3, as indicated by dotted lines
1n Fig. 3. These movements of the members 2
and 3 will compress the coiled spring 5, and as
the ridge 23 approaches the groove 2l, the spring
5 forces it into the next groove 2I with a snap.
In this llas-h position, a downward pressure on
the button 4 will force the flange II ’ into contact
with the rivet 2B, thus closing the electric circuit,
as indicated in Fig. 4.
Release of pressure on the
button 4 will permit the spring 5 to lift, or raise,
the top member 2 of the slide I, thus breaking the
contact between the flange I I’ and the rivet 26.
A repetition, or continuation, of the forward
pressure, which moved the slide from open cir
cuit position to flash position, will move the slide I
to closed circuit position, as indicated in Fig. 5,
in which position the bottom portion I3 of the
slide I is in continuous contact with the contact
rivet 26. A backward pressure on the button 4
will return the slide I to open circuit position, and
as it rides into this position, the lock lug 3| will
snap into position in the slot I2. The button 4
projects upwardly through an elongated opening
32 formed in the housing I9, and the top portion 9
of the member 2 of the slide I is long enough to
cover the opening 32 in all positions of the slide I.
Clearance openings 2'! and 33 in the tube I7 and
the lead strip 24 respectively prevent short cir
cuiting through the rivet 26, or the eyelet 28.
Figs. 8 and 9 illustrate a modiñed form of single
contact switch in which the contact rivet and eye
lets, shown in Figs. 3-7, inclusive, are eliminated
by the use of an insulation covered lead strip 34.
The strip 34 has its metal core 35 uncovered at
3.6 to connect a lamp, and also uncovered and
formed into a loop at 3'.' to form a contact for
the ilange il’. The strip 34 is supported in a
slot 38, formed in the tube I‘I, and the tube is
formed with a clearance opening 39 under the
end 3l, to prevent a short circuit. The opera
tion is the same as that described for the con
struction, shown in Figs. 3-7 inclusive.

to the rivets 42 and 42', shown in Fig. 12. The sued August '1, 1934, to Wesley J. Oiiicer and
assembled switch and switch lead `may be assem
bled on a tube I1 by inserting a bent portion 59
65 of the switch lead 55 through an opening 59,
formed in the tube I1. The housing 59 may be
secured on the tube l1 by inserting tabs 6 I , formed
on the housing 50, in slots |52, formed in the tube
I1 and bending the tabs against the inner sur
face of the tube I1, as indicated in Fig. 16, or the

Figs. 18-21 inclusive, illustrate a modiñed form
of ilashlight switch in which the stations are lo
cated in co-operative relation with the housing,
Blake A. Seaver. When va single housing is used
in co-operation with the switch slide, opposing 65
side walls of the housing conñne the members 2
and 3 of the slide and prevent side slippage of
these members, relative to each other, but in a
double housing, like the housing i9', shown in
section in Fig. 26, means must be provided for
preventing side, or lateral slippage, of the upper
and lower members of the switch slide, relative
to each other. The upper member 2’ is notched
at |09 and IDI, and the end flanges i5 of the
lower member 3’ are formed with projecting lugs 75
4
2,138,387
l G2 and l U3, which are located, or engaged, in the
notches iOû and lûí, respectively. When assem
bled in a housing I9', the button 4, being con
iined within a slot 32 (see Fig. 15), in the hous
ing, prevents side, or l-ateral slippage, of the up
per member 2'. The side wall I9” of the housing
t9’ prevents side or lateral slippage of the bottom
member 3’ in one direction, and engagement of
the lugs |02 and |03 of the lower member` 3' in
notches |69 and IUI of the upper member 2',
prevents side slippage of the member 3’ in the
opposite direction. As the lugs £02 and |03 are
formed on one side only of the member 3', the
member 3’ may be quickly and easily slipped into
the member 2’ in -assembling operations. The
side edges |34 of the bottom portion i3’ of the
member 3’ are bent upwardly to serve as a re
taining means for the helical spring 5, and also
to reinforce the portion I3’. This construction
prevents the spring 5 from working sideways out
of proper alignment with the members 2' and 3’.
