Abstract: The present invention provides an electro-mechanical programmer/timer having a plurality of switches actuated by a rotating program cam with each of the switches tracking a separate cam track on the cam. The program cam is indexed by a pawl which engages ratchet teeth on the program cam. The pawl is oscillated by engagement with a sub-interval cam driven by a motor drive. At least one of the switches following the program cam is a single-pole double-throw switch with the center blade thereof actuated by a cam follower lever operated by a separate track on the sub-interval cam.

Abstract: An automotive light switch assembly having a rotatable/pull-push type user actuator extending from a housing adapted for dashboard mounting. The rotary actuation controls the on/off functions for both the parking and headlamps and the pull-push actuation controls the on/off function for the vehicle interior lights. A light pipe illuminates, from a stationary source a translucent lens on the rotatable/pull-push actuator to facilitate user location. Stationary translucent lenses are illuminated to indicate the particular function position that has been selected. A pair of spaced oppositely disposed wheel or disc-type actuators are provided below the rotatable/pull-push actuator for controlling respectively headlamp illumination distance and interior light intensity. A light pipe illuminates, from a stationary lamp source, a translucent lens on each wheel to indicate the wheel position. Stationary illuminated indicators display the function/level selected by each individual wheel position.

The spring biases the cup-shaped contact in a direction to seat the flange against the stationary contacts. When the cartridge is inserted in a bore, the bead ring is compressed to seal the cartridge in the bore.

Abstract: For protecting the pump of a carpet cleaner, the cut-out terminals 16, 15 are commanded by the pressure of fluid in passage 11, 12, 13 which communicates with volume 22 having as an upper wall a flexible diaphragm 24. A fluid tight and electrically insulating housing 9 has a fixed boss portion 19 which is surrounded by a mobile annular permanent magnet 25 carried by diaphragm 24 and which guides a central mobile permanent magnet 20 which drives a mobile contact 18 up or down, closing or opening terminals 15, 16. High pressure at 11 drives diaphragm 24 and magnet 25 upwards, which attracts magnet 20 upwards, and connects terminals 15, 16 via mobile contact 18.

Abstract: A rotary position detector switch suitable for use in hydraulic fluid and having at least three stationary parallel conductive strips of tin plated low carbon steel intermittently over molded with intermediate portions exposed. An insulated rotor has a bus with spaced hardened steel pins with hemispherical ends slidably mounted thereon and bias springs connecting the pins to the bus. One stationary strip is completely exposed and is electrically common and in continuous contact with one pin. For each selected different rotor position combinations of two other pins contact different exposed portion of the remaining strips to give a discrete electrical indication, for each rotor position.

Abstract: "A stalk switch for automotive steering column having the stalk lever pivoted about a vertically disposed cross-pin having its ends mounted with ball and socket connections to a slider. A push button in the end of the lever moves the lever and slider for effecting switching by one set of contacts and pivoting the lever about the axis of the cross pin effects switching of another set of contacts. Pivoting the lever about an axis transverse to the cross pin axis causes the cross pin ball ends to pivot in the sockets and moves another slider for effecting switching of a third set of contacts. A rotatable ring is mounted on the lever and is rotatable for effecting switching of a fourth set of contacts.
