ABSTRACT:
An electromechanical timer arrangement includes a rotatable cam having a cam surface for actuating an associated switch. An inhibit member is movable between an active position and an idle position. In its active position, the member engages the switch and prevents cam actuation of the switch. In its idle position, the member permits normal cam actuation of the switch. In controlling a dishwasher the active and idle positions are user-selected non-heated and heated drying cycles and the switch controls energization of the heater. The cam surface is contoured to close the switch for heated drying. Moving the member to its active position opens the switch, regardless of the cam position, for non-heated drying.
