To provide a push switch operating with pressing sound of a button.
The push switch has an upper case 1 having a cylindrical part 1b, the button 3 slidable along the cylindrical part 1b, a rotor 5 which slides and reciprocates while rotating in a predetermined direction using a long shaft of the cylindrical part 1b as a rotary shaft in accordance with reciprocating movement of the button 3 and has a flange 5a in a bottom part, a connection piece 4 inserted into the rotor 5 and locked in the flange 5a, and fixed terminals 2a, 2b, 2c provided in the case in opposition to the connection piece 4. The rotor 5 rotates by a predetermined angle every time when the button 3 reciprocates to perform ON/OFF operation. The connection piece 4 is provided with an arm 4a bent in the directions of fixed terminals 2a, 2b, 2c. This arm 4a is elastically bent in accordance with changes of distance between the fixed terminals 2a, 2b, 2c and the rotor 5 which occur when the rotor 5 slides and reciprocates to keep the contact between the fixed terminals 2a, 2b, 2c and the connection piece 4.
