<p>The switch provides the combined control of turn indicators and various levels of vehicle lighting as well as audible and visual warning signals. The switch has a multiple cam, fixed on two shafts which are axially traversed by the operating lever. The driven shaft has some angular freedom relative to the driving shaft, which carries a three position indexing cam, a stop cam, and a cam for the lighting switch. - The driven shaft carries cams for signal and headlamps, an indexing cam, and a cam to cause the driven shaft to follow the driving shaft. The driving shaft has three teeth engaging the blade of a ratchet, rotating on a carrier which operates against a stop during the positioning of the lever in a momentary contact position. GBAB- GB2135126 B A multi-function switch for use in a vehicle for controlling the external lighting of the vehicle, which switch comprises an elongate control lever, a driving cam shaft and a driven cam shaft, the lever being coupled to said driving cam shaft whereby rotation of the lever about its longitudinal axis to any other angular position rotates said driving shaft, said driving shaft being rotationally coupled to said driven shaft by a lost motion device to permit a limited angular relative rotation therbetween, said driving shaft including one or more cams to selectively operate one or more electrical contact sets upon said rotation of the lever to one or more angular positions, and wherein said lever is pivotable, against a restoring force, from its normal position to an unstable position, said pivoting causing rotation of said driven shaft relative to said driving shaft, said driven shaft including one or more cams to selectively operate one or more associated electrical contact sets upon said pivoting of the lever to said unstable position.</p> |
