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.
