There are three spring blades held in working relationship to a camstack which provide the making of two different and distinct circuits simultaneously by substantially simultaneously closing electrical contacts carried by the blade. Of the three blades a lower level blade engages cam contours of the camstack, a middle level blade includes a follower which engages a hub portion of the camstack, while the upper level blade extends freely above the middle blade.

Timer blade arrangement

An electrical contact blade is manually operated through an actuator to close a circuit to a main power supply and another electrical contact blade is operated off of a cam to engage the manually operated blade to complete a program electrical circuit.

Line and program switch assembly for a timing mechanism

A control system for an appliance having a plurality of different operational cycles, provides cam operated switches for controlling the coupling of electrical power to the appliance, the switches including a plurality of rotatable cams for operating the switches in response to the rotational position of the cams, the switches being adapted for electrical rotation of said cams, a digital electronic control circuit for controlling the electrical cam rotation, the control circuit including circuitry for receiving a selection of any one of the cycles for the operation of the appliance, and a second circuit coupled between the switches and the control circuit and responsive to the circuitry for receiving for supplying information on the rotational position of the cams to the control circuit to enable control of the electrical rotation in accordance with a cycle selection.
