Abstract

A timing device, for turning a cooker (for example) on after a first timed period and off after a second timed period, has a pair of coaxial drum- shaped face cams 15 and 16, manually rotatable to select the two timed periods respectively. Between the cams lies a lever 26 mounted on a spindle 20, the spindle having limited freedom for axial movement to operate a switch 24 which controls the cooker. The spindle and lever are rotatably time driven via gears 22, 21 so that the lever moves over the cam faces of the cams. The two cams are manually settable and cause the lever to rock in turn about each end, carrying with it the spindle, so as to operate the switch at the set times. <IMAGE>
