ELECTROMECHANICAL TIMER SWITCH

摘要

An electromechanical timer switch has a timekeeping, rotating programme ring (3) rotatably mounted on a hub (2) fastened on one side. Programmable riders (17) arranged on the programme ring (3) act on an electric contact arrangement (22) according to a switching programme. A manually operated switching device provided with a pin-shaped swivelling actuator (1) and arranged on the front face (16) of the timer switch beside the programme ring (3) can actuate the electric contact arrangement (22) independently of the switching programme. Cam-shaped fastening elements (44, 39) are provided for fastening the built-in housing (36) containing the timer switch in electrical control panels (38) or other supporting surfaces. The switching device together with the actuator (1) is arranged inside the hub (2) and therefore runs inside the programme ring (3).
