PURPOSE:To use movable contact pieces in common and to reduce the number of parts by constituting the movable contact pieces of conductive leaf springs, fixing and supporting respective movable contact pieces at their centers, arranging fixed contacts at positions corresponding to the free ends of the leaf springs and arranging respective operation members at positions corresponding to the free ends. CONSTITUTION:Three arm parts 45a-45c for respective switches are formed on a switch leaf 45 and constituted of conductive elastic leaf springs the tips of the lower bending parts 45d, 45e arranged on the center part form claw parts and the bending parts 45d, 45e are fitted to a circuit substrate 42 by bending the claw parts to the back side through slits formed on the circuit substrate 42, and connected to the ground on the substrate 42. Respective arm parts 45a-45c have respective contacts 45'a-45'c, which are opposed to fixed contacts 42'a-42'c formed on the substrate 42. Knobs 47a-47c are formed correspondingly to respective arm parts 45a-45c.
