ABSTRACT:
A timer for controlling an appliance includes a top subinterval circuit which is used to control an appliance function. The top subinterval circuit has electrical circuit blades which are movable to open and to close the top subinterval circuit. The timer also includes a subinterval lever which contacts a subinterval cam. The subinterval lever is movable in response to the subinterval cam to impart motion to the circuit blades. This movement acts to open and to close the top subinterval circuit. Moreover, the timer includes a masking lever that engages the circuit blades to prevent the closing of the top subinterval circuit. Thereby the motion of the subinterval lever is masked.
