ABSTRACT:
An electrical circuit electrically connects a timer motor for a timer in parallel with a thermostat means, the thermostat being electrically connected in series with a heating mechanism. With such a connection, heat may be applied to a drying apparatus while the timer is not running and when the thermostat opens to shut off the heat, the timer motor will run to operate the timer to advance the timer through the time cycle.
The timing mechanism or timer for the control system includes at least one set of switching structures responsive to a cam, the switching structure including a terminal block, and first and second electrical contact blades cantilevered on opposite sides of the terminal block and cooperating electrical contacts to open and close electrical circuits.
