Claims (1)

[Scope of claim for utility model registration] A main switch for cutting off the power after a set time, a reversing switch for controlling the water flow generation motor in forward and reverse directions, a main cam and a main cam for controlling on/off the main switch and the reversing switch, respectively. A washing machine is provided with a time switch equipped with a reversing cam, and a water flow selection means provided on a panel for selecting a water flow state during washing, and the reversing cam has first and second cams each having a different cam surface shape. It has a second cam surface, and by relatively moving the reversing cam and the reversing switch, the reversing switch is controlled on and off by the first cam surface and on and off by the second cam surface. A cam surface switching means is provided for switching between the water flow selection means and the cam surface switching means, and the water flow selection means and the cam surface switching means are such that when the water flow selection means is operated, the sliding contact position of the reversal switch is set to a first position of the reversal cam surface. A washing machine characterized in that a cam surface and a second cam surface are connected so as to be switched between each other.
