Filed:

Jul 28, 1989

Appl. No.:

7/386371

Inventors:

Richard C. Bogda - Elmhurst IL
George D. Georgacakis - Skokie IL

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 4310

US Classification:

200 30R

Abstract:

An electromechanical programmer assembly for controlling electrically operated appliances having a rotatable cam drum operable upon motorized advancement to actuate and deactuate plural program switches for controlling appliance functions. A user actuated shaft is rotated to select the desired cam drum position for program selection. Axial movement of the shaft causes a cam thereon to lift a slider for opening a line power switch for controlling the motorized cam drive and engaging a friction detent on the cam drum for resisting rotation of the drum and to provide a tactilely sensed position indication to the user. Axial movement of the shaft to effect dropping of the slider closes the line power switch and disengages the detent.

International Classification:

US Classification:

Abstract:

A combination programmer and line switch for an appliance having a rotary program cam and a timing motor connected for advancing the cam. An upper line power contact blade is moved between high and low positions by a manual actuator. A lower contact blade is maintained stationary and is adapted for connection to certain appliance load functions. An intermediate program contact blade series connected to the timing motor has a follower biased against the program cam and is adapted for connection to all appliance functions. With the upper contact in the high position, the motor circuit is open for all positions of the program and in the low position the timing motor is energized. Alternatively, the program cam may include a line contact switch override to maintain the intermedaite blade in contact with the upper blade for both positions of the manual actuator.
