A side push switch includes an insulative housing ( 1 ), a periphery contact ( 22 ), a central contact ( 25 ), a dome ( 3 ), a lever ( 5 ) and an actuator ( 5 ) mounted on the lever. The dome is disposed over the central contact and electrically connects with the periphery contact. The lever is formed with a transversal branch ( 51 ) and a longitudinal branch ( 52 ) extending from the transversal branch. A pair of trunnions ( 510 ) are respectively formed at opposite ends of the transversal branch. A depressing portion ( 520 ) is formed on the longitudinal branch. An actuating follower ( 521 ) is formed at a free end of the longitudinal branch. The actuator has a ramp ( 45 ) engaging with the actuating follower of the lever thereby causing the lever depressing the dome to connect the periphery contact and the central contact.
