A multiple contact switch has a plurality of contact areas spaced across a base member, a plurality of cantilevered spring contact members mounted side-by-side on the base member with contact portions overlying the contact areas, and a rotary cam member extending over the spring contact members to push the contact members down to make contact. A cam surface is provided for each contact member. The cam member is actuated by a remove actuating member and in a line switch for a telephone set, the switch can be mounted on the base of the telephone set with the cam actuated by a flexible cable which in turn is actuated by means depressed when a hand set is replaced.
