Abstract
A pushbutton switch includes an upper case (1) having a cylinder portion (1b) and a button (3) which is capable of a sliding motion along the cylinder portion (1b). A rotor (5) having a flange (1a) at the bottom thereof performs a sliding reciprocating motion while rotating in the predetermined direction responding to reciprocating motion of the button (3) by setting the axis of rotation as the long axis of the cylinder portion (1b). A contact segment (4) is inserted in the rotor 5 and stationary terminals (2a, 2b, and 2c) oppose the contact segment (4). The rotor (5) carries out a predetermined angle rotation for every reciprocating motion of the button (3) to effect alternating ON/OFF switching action. Arms (4a) curve toward stationary terminals (2a, 2b, and 2c) and elastically buckle in accordance with the variation in distance between stationary terminals (2a, 2b, and 2c) and the rotor(5) when the rotor (5) performs a sliding reciprocating motion.
