ABSTRACT:
A control mechanism in combination with an electric motor assembly in which an output shaft having a cam surface is connected to the electric motor through a gear train located in a housing. A switch block assembly is on the housing. First and second arms extend from the switch block assembly with the first arm having a contact near the free end thereof and the second arm intersecting the first arm. The second arm rides on the cam surface of the output shaft and has a contact which moves in and out of engagement with the contact of the first arm. The first and second arms are disengaged when the output shaft begins a cycle of rotation and are engaged when it completes the cycle. The switch block assembly includes a base formed integrally with the gear train housing. The base has posts and a central block located between the posts. A switch top includes a pair of blocks, a cross member connecting the blocks and a passage formed in each block. The passages receive the posts of the base with the cross member resting on the base center block. Slots are formed in the cross member between the base and the blocks. Quick connect terminals extend through the slots.
