DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a multiple
circuit simultaneous on / off switch for four channel speaker car stereos etc. which
simultaneously opens and closes four speaker circuits, as shown in FIG. As shown in the above, it
is an improvement to Sui and Tuchi. In the switch shown in the figure, the movable contact plate
(3) with contacts provided on both sides of the "H-shaped" slope spring is positioned between the
upper and lower facing fixed contact plates (1), with holes t% -Set the switches as a set of
switches, and arrange these switches in a row with an appropriate distance between any set of
switches (M to D), and set 1 near the base of each arranged unit switch. @ Insulated Yonagodai
(embedded in 4+, on one contact of the movable contact plate (3) of each group to D, always in
contact with the contact of one fixed contact plate (2) It is. And the simultaneous opening and
closing of this switch is the simultaneous pressing and release by the operation 48-49549-03 '&--t (3) K of the movable contact plate (3) in each unit switch-DK. According to, 6 movable
contacts! This is done by bringing the contact of (3) into and out of contact with the contact of
the fixed contact plate (1). Although this switch company can open and close a plurality of
circuits simultaneously as described above, the biggest problem is that the top of the bent

portion of the movable contact @ (3) formed in the "shape" is one fixed contact [(1) Because they
are close in distance to each other, they can not produce in J6 a capacity that meets the required
withstand voltage standard for the distance * between the T-plates. For example, when a voltage
of laoov is applied for one minute between contact plates, the test can not be put to practical use
unless there is a sufficient distance to withstand K. Movable contact! Setting the distance
between the top of the bent portion of (3) and the fixed contact plate (1) to the above-mentioned
appropriate withstand voltage distance is a factor that makes it difficult to handle easily and does
not increase the home product of the switch. It is necessary to change the bending angle of the
curved part, especially in order to adjust the spring pressure of the movable contact plate to v4. 49549-04-One side, there is a large fk11 point at which the above distance must be considered
in the side of □ 4. Therefore, the present invention is to solve the above conventional problems.
The inner gaK contact a / 61 has 9 longitudinal and "shaped" movable contacts [(7), and a
movable contact plate (9) with a contact point (8) on the inner side that is the same length and
straight as the contact plate. ), And short and straight contacts QOQl) on both sides compared to
these contact plates, provide fixed contact plate o2 and move the movable contact plate (9 +
(fixed contact plate (2) in the middle of 71) Then, the contact point (6) of the movable contact
plate (7) of "Hen form" is made into a set of unit switch quantity with the gold of the book which
is made contact with the contact point QGK of the intermediate fixed contact plate (b) As a row
with a fixed distance between any combination of unit switches IC and H47 switches.
Near the base of each switch is embedded in one insulating terminal block rL3, and the tip of the
movable contact plate (9) of each position switch 1 to 11 is provided with empty * i 4 on top The
actuator (d) K is embedded, and the above-mentioned protrusion (14 is brought into contact with
the movable contact [(7) 轡 in the form of "、", and the spring pressure of the movable contact
plate (7) is adjusted to The contact t of the contact point (6) of the plate and the contact αO of
the fixed contact plate 1 was t-corrected. The invention relates to a plurality of circuits
simultaneously opening and closing switches 48-49549-055 switch. Since the draft switch has a
mud-like structure and nine. The circuit connected with the identification contact plate (2) of
each basic switch and the movable contact plate (9) is open, and the circuit connected to the
fixed contact plate 03 and the movable contact plate (7) is closed. Therefore, if the unit switch is
to be closed simultaneously, the operator should be turned in the direction of the movable elbow
plate 7 of the "shaped". The movable contact metal (9) of the unit switches 1 to H moves in that
direction, and the contact (8) of the same contact plate and the contact (ii) of the fixed contact
plate 2 simultaneously contact, and the movable contact plate (7) It is pushed up and its contact
(6) separates from fixed contact plate C's two contacts αG. That is, the contact of the unit switch
X- 単 位 is simultaneously opened and closed by the pressing of the operation element θ9. If the
operator is turned back in the direction Wc opposite to the above and returns to the former
position, each contact point of the unit switch operates on the upper pole and the base pair, and
the contacts are simultaneously moved. Thus, according to the present invention, the operation
of the operating element α9 (simultaneous opening and closing of plural circuits is performed,

so that all the failure points of the conventional switch can be eliminated. 4B-49549-06, 2X, 26
or the above-mentioned conventional switch of this type, as shown in FIG. 1, movably with the
movable contact plate "shaped" in the middle between two fixed contact plates The tops of the
bent portions of the contact plates are disposed close to one fixed contact plate. Although it is
difficult to easily set the necessary distance between the terminal plates in terms of withstand
voltage, the switch according to the present invention is, as described above, a movable contact
plate (force) of each unit switch X-H. Since it was installed on the outside, the apex of the bent
portion was completely unrelated to the in-between point at which the distance between the
terminal plates was flooded, and the bend angle of the 9 bent portion was freely adjusted, and its
contact point (6) The contact between the fixed contact piece (6) and the saddle point (a) can be
made optimally positive. Therefore, the productivity of the multiple circuit simultaneous on / off
switch can be significantly improved. In the present invention, the length of the fixed contact
plate αa is shorter than that of the other contact plates, and the length of the movable contact
plate (force (9)) is longer than that of the other contact plates. The contacts of the movable
contact plate +71 and the intermediate fixed contact plate 0 are in constant contact, and the
movable contact plate (9) end of each of the unit switches E to H has one operating element (1!
Buried in 3 and 4 B-4954! )-Α 7, 1 acceptable? 1113 The point plate (7) end is brought into
contact, and as described above, the contact of the unit switch E---can be opened and closed
when sweeping of the force switch Q9 makes it possible to open and close the switch 09. Proper
form of "He-shaped" movable contact plate (7) Now 7) 4) in the movable contact plate of each
unit switch is not uneven due to the original force and it operates in f-sense, the accuracy of each
contact Simultaneous contact and separation will take place. Therefore, it is IkA one as a multiple
circuit simultaneous open / close switch for 4 ch 2 nonel spin car stereo etc.
