Timer switch assembly

Claim 1

Timing apparatus comprising motor means including a supporting member and rotatable output shaft rotatable through a revolution in a prescribed period of time, switching means operatively connected to said supporting member of said motor means for alternating switching between two discrete positions for respectively operating electrical output devices, indicating means operatively connected to said output shaft for movement in unison with said output shaft, and for selective independent movement with respect to said output shaft in response to adjustment for adjustably setting the times within said prescribed period of time at which said switching means will be operated to effect such switching between the electrical output devices, and actuating means operatively connected to said supporting member of said motor means, directly connected to said switching means and being operatively contacted by said indicating means for periodic movement between opposed first and second positions in response to displacement of said indicating means, said actuating means including biasing means for resiliently snapping and maintaining said switching means in either one of the two discrete positions whenever said actuating means is correspondingly in one of said first and second positions, said actuating means includes an oscillating arm connected to said supporting member of said motor means for oscillatory movement between said first and second positions, camming means directly connected to one end portion of said oscillatory arm and being positioned to be struck by said indicating means, said biasing means directly interconnecting said actuating means to said switching means for snapping said switching means to said either of the two discrete positions in response to said oscillatory movement of said oscillating arm.
