ABSTRACT:
A time switch for starting and stopping an electric appliance at set times comprises an electric timer, a display housing a display for the set times, and a switch housing having a concave. The switch housing has input terminals, output terminals, and a switch unit for connecting and disconnecting the electric appliance to and from an power source in accordance with an output from the timer. The time switch includes a coupling member for connection of the display housing to the switch housing. The coupling member comprises a cylinder through which lead wires extends between the timer and the switch unit. The coupling member is movably supported to the switch housing along a center axis of the cylinder so that the display housing can move between a normal position where the display housing fits within the concave and an extended position where the display housing projects out of the concave. The coupling member is rotatably supported to the switch housing such that the display housing can rotate about the center axis of the cylinder at the extended position. This time switch presents an advantage that it is easy to check the set times on the display irrespective of installation angle of the time switch to a switchboard or the like.
