Abstract:
A control shaft and knob assembly includes a control knob having a slot defined therein. The assembly also includes a control shaft which (i) has a bore extending therethrough, (ii) includes a spring arm which is positionable within the slot of the control knob, and (iii) has an opening defined therein. The assembly further includes a locking pin having a first retention member secured thereto. The locking pin is positionable in the bore of the control shaft. When the locking pin is positioned in the bore of the control shaft (i) the locking pin is positioned to inhibit inward deflection of the spring arm, and (ii) the first retention member is received into the opening of the control shaft. A method of securing a control knob to a control shaft of an appliance timer is also disclosed.

Abstract:
A device enables a camstack in an appliance timer to be rotated without applying electrical power to the switches of the appliance. The device includes a knob having an elongated actuator extending from a lower surface of the knob to an outboard end, the elongated actuator having a shoulder between the outboard end of the elongated actuator and the knob, a camstack shaft for rotating a camstack used to selectively engage cam followers for controlling operation of an appliance cycle, the camstack shaft including a passageway for telescopically receiving the elongated actuator extending from the knob, a switch actuator having a hub and a radial flange, the hub having a passageway for receiving the outboard end of the elongated actuator up to the shoulder so the actuator is axially moved by depression of the knob, a switch having one contact mounted on one end of a resilient member configured to urge the one contact toward another contact to close the switch, and a slider having a first end and a second end, the first end of the slider contacting the radial flange of the switch actuator and the second end of the slider being coupled to the resilient member of the switch so that depression of the knob moves the radial flange of the switch actuator with respect to the first end of the slider to urge the resilient member and the one contact away from the other contact to open the switch.
A gear train is connected to a motor carried in a housing and has an output member extending into another housing, the output member having at least one cam lobe. Electrical switch means carried in the second housing are responsive to the cam lobe.
An electrical contact arm is spring biased against electrical paths by a coil spring which is carried on a hub of a rotating member which also carries the electrical arm. An electrically conductive path is also carried by the rotating member to provide switching functions.

Abstract:
An automobile brake switch assembly including a mounting clip and two brake switches, each brake switch including a threaded, cylindrical plunger housing. The mounting clip includes two hollow, cylindrical sleeves, each having an inner diameter slightly larger than the outer diameter of the threads on one of the brake switches. The sleeves are integrally molded, together with a plate that joins them, out of acetal plastic. Each sleeve includes a thread-like tooth molded about the inner circumference and located approximately centrally in the cylinder. Four slots are formed in each sleeve parallel to and spaced about the cylindrical axis, the slots cutting the tooth to form four teeth. The slots permit expansion of the teeth when the threaded plunger housing of the corresponding brake switch is pressed into the sleeve so that the threads may ratchet on the teeth. The teeth and inner surface of the sleeve mate with the threads to firmly hold the brake switch without pressing into the walls of the brake switch plunger housing.
An axially spring biased plunger has a cam which upon simultaneous engagement with a pair of switches opens one of the switches while closing the other.

Abstract:
A timing mechanism has an intermittent drive mechanism disposed in axial alignment with a cam means and between an end plate of the timer housing and a plate carrying a constant speed drive means. There is also included an adjusting means permitting manual setting of the cam means with respect to the switches responsive thereto.
