In a tape recorder provided with a power jack which includes a rod-like conductive member, a relay conductive member insulated from the rod-like conductive member, and an elastic conductive member having elasticity and being capable of moving a first position, at which the elastic conductive member is separated from the relay conductive member by inserting a plug to the power jack, and a second position, at which is in contact with and electrically connected to the relay conductive member, a main switch for the tape recorder comprises a cylindrical rotary member having an inner periphery, an outer periphery and a recess formed in the outer periphery. The rotary member is adapted to snugly fit on the rod-like conductive member of the power jack when inserted thereinto, and is rotatable on and about the rod-like conductive member between a first position, at which the outer periphery and the elastic conductive member are in contact with each other and the elastic conductive member is located in the first position, and a second position, at which the recess corresponds to and face the elastic conductive member to locate the elastic conductive member in the second position.
