Abstract
An assembly method and a thermostat for an electric/gas oven are provided. An enclosure formed by a base and a cover for enclosing a switch subassembly includes axially aligned channels extending through opposed walls and external keying and positioning features. A pair of axially aligned actuators are received within the axially aligned channels. A frame having cooperating keying and positioning features positions and supports the enclosure containing the switch subassembly and supports both a temperature responsive subassembly and a spindle subassembly in operative position with respect to the actuators.
Claims9
A thermostat for use with an oven of an electric or gas range comprising:
- an enclosure;
- a first electrical contact;
- a second electrical contact;
- said first and second contacts disposed within said enclosure, and said first and second contacts having terminal blade portions extending outside said enclosure for electrical connections;
- a switch spring arm disposed within said enclosure and having a fixed end coupled to said first electrical contact and a free end moved from a contacting position and a noncontacting position with said second electrical contact;
- a pair of actuators disposed on opposite sides of said spring arm and being axially aligned for coupling forces to said switch spring arm;
- said enclosure having axially aligned channels extending through opposed walls for slidably receiving said actuators;
- a frame supporting said enclosure;
- a temperature responsive subassembly supported by said frame including means for movement responsive to changes in oven temperature;
- said temperature responsive movement means being supported in operative position with respect to a first one of said pair of actuators;
- and
- a spindle subassembly supported by said frame including means for movement responsive to manual rotation of a spindle;
- said spindle movement means being supported in operative position with respect to a second one of said pair of actuators.
