When the dryer is connected to power, power is applied<br />
to the input terminals of switches A <strong>and</strong> B of the timer.<br />
The switches contacts which are spring-loaded closed,<br />
are opened by pushing down on the switches arm. Switch<br />
Acontrols power to the timer motor, indicator light, thermal<br />
limiter, start switch, dryer motor <strong>and</strong> door switch. Switch<br />
B controls power to the fabric selector switch, control<br />
thermostat, safety thermostat <strong>and</strong> the heater source<br />
circuit.<br />
The switches are controlled by the switch control cam.<br />
When the point of the tooth of the switch cam is engaged<br />
with the extrusion of the cam switch arm, the cam switch<br />
arm pushes down on the switches arm, <strong>and</strong> opens<br />
switches A <strong>and</strong> B.<br />
