Abstract: An electrical switch construction having a stationary frame carrying an electrical switch provided with different operating conditions and an actuator pivotally mounted directly in the frame and operatively associated with the switch for operating the switch to the different conditions thereof in accordance with the pivot position of the actuator about its pivot point in the frame. A timer member is operatively associated with the actuator for repetitively pivoting the actuator about its pivot point to cause the switch to be repetitively in one condition thereof a certain percentage of a certain increment of time and for being in another condition thereof for the remainder of the certain increment of time. An adjustable member is operatively associated with the actuator for changing the pivot point thereof in the frame and in relation to the switch and thereby selecting the amount of the certain percentage of the certain increment of time within certain limits.

Abstract: An electrical swtich construction having a self-contained and completely operable electrical switch assembly disposed in a protective envelope and having leads extending from the assembly and projecting externally through an opening in one end of the envelope. A removable end closure is carried by the envelope and closes the opening of the one end thereof, the end closure having apertures therethrough and removably receiving the leads therethrough whereby the self-contained switch assembly is adapted to be carried by the end closure away from the protective envelope when the end closure is removed from the one end of the protective envelope and the self-contained switch assembly is adapted to be removed from the end closure solely by pulling the leads out of the apertures thereof.

Abstract: A timer controlled control system for an apparatus having two controlled devices and a timer construction operatively associated with the devices to operate the same, the timer construction having a single timer provided with a pair of selectors respectively operatively associated with the devices and each selector being adapted for selecting the total time period the timer is to operate both of the devices and each selector being adapted for selecting a certain percentage of the selected total time period the timer is to operate its respective device concurrently with the other device, each selector means being manually operable.

Abstract: A microwave oven having an electrical switch construction provided with an electrical switch that in one operating condition thereof operates the power unit of the oven and that in another operating condition thereof turns off the power unit. A timer is operatively associated with the switch for causing the switch to be repetitively in one of the conditions thereof a certain percentage of a certain increment of time and for being in another condition thereof for the remainder of the certain increment of time, the timer being adapted for selecting the amount of the certain percentage of the certain increment of time within certain limits whereby a slow to fast defrost cycle of the oven can be provided. The timer includes a rotatable cam member having a cam part for caming the switch to one of the operating conditions thereof during each revolution of the cam member, the cam part of the cam member being radially moveable relative thereto.

Abstract: An electrical switch construction having an electrical switch provided with different operating conditions, the construction having a timer moved actuator operatively associated with the switch for causing the switch to be respectively in one condition thereof a certain percentage of a certain increment of time and in another condition thereof for the remainder of the certain increment of time. The actuator is adapted for selecting the amount of the certain percentage of the certain increment of time within certain limits.

Abstract: A timer construction having a timer motor and a selectable time period unit adapted to be interconnected to the timer motor of a clutch construction to drive the time period unit for a selected time period, the clutch unit including a first rotatable member driven by the timer motor and having a plurality of teeth arranged in a ring-like circular array and a second rotatable member being axially movable and having a plurality of teeth on the outer periphery thereof. The second member is operatively interconnected to the time period unit and is adapted to have some of its teeth mesh with at least some of the teeth of the first member to be driven thereby when the second member is axially moved into the circular array of teeth of the first member.

Abstract: An electrical switch construction having an electrical switch provided with different operating conditions, the construction having a timer moved actuator operatively associated with the switch for causing the switch to be repetitively in one condition thereof a certain percentage of a certain increment of time and in another condition thereof for the remainder of the certain increment of time. The actuator is adapted for selecting the amount of the certain percentage of the certain increment of time within certain limits.

Abstract: A joint construction of two members each having one surface thereof disposed against a surface of the other member. One of the members has a part thereof punched through an unblanked part of the other member beyond the other surface of the other member, the part of the one member being subsequently staked to the other surface of the other member to secure the members together.

Abstract: A cut-back thermostat construction having a thermostat arrangement and a timer carried by a frame in such a manner that the timer will cut back the temperature setting of the thermostat arrangement by moving an electrical switch unit of the thermostat arrangement relative to a temperature responsive switch operator when a predetermined time is reached by the timer. A movable actuator is carried by the frame and is operatively associated with the switch unit to be adapted to cause a certain movement of the switch unit relative to the switch operator when the actuator is moved from a first position thereof to a second position thereof by the timer reaching the predetermined time.

Abstract: A timer switch includes a snap acting switch blade moved by an operating member which is biased against a side of a guideway which has inclined camming surface portions for camming the operating member under the bias force to respective opposite ends of the guideway.
