The customer then advances to the machine and

It is further proposed, in the present invention,
to provide means. whereby after consummation

It is further contemplated to visibly indicate

The switch 5 is mounted at the machine.
The remote control switch 4 is here shown as
a micro-switch operable by means of a lever 6,
the far end of which carries a roller 1 adapted
to roll on the surface of a cam wheel 8 having
a notch 9 in which the roller rests in an initial
cam position, with the micro-switch open. When
the cam is turned by means of the shaft !0, to
