HOW THE CLUSTER OF SWITCHES WORKS
1. See Vend Motor and cluster switches in stand-by position Figures 1 and 2.
Arm of Vend Motor Switch A is in cam notch - Figure 2.
Arm of Cam-Hold Switch B is on top of cam - Figure 2.
Arm of By-Pass Switch C is on top of cam - Figure 2.

A)
Set-up credit.
B) Push a selection. (Pushing of a select switch causes the vend motor to run and the arm of the cam-hold
switch to drop into the cam notch). Then...
C) the cam-hold switch runs the Vend Motor through the notch and
D) the arm of the Vend Motor switch reaches the top side of the cam and breaks the circuit to the vend
relay (cancels credit) and causes the vend motor to continue to run.
E) A fraction of a second later, the bypass switch arm reaches the top side of the cam and forms a bypass
around the vend motor switch. If a jam occurs, all other circuits work.
F) The vend motor continues to run to stand-by position..
