ABSTRACT:
A push lock switch includes a switch body having walls and a plurality of the terminals each of which has a fixed contact. The switch body has a cam groove formed on one of the walls. A part of wall defining the cam groove serves as a hooking recess. The switch body has a lock pin and a slider movable between a projecting position and a retracted position. An end of the lock pin is inserted in the cam groove. The slider is held at the retracted position by engaging the end of the lock pin to the hooking recess. The switch body also has a leaf spring mounted on the slider. The leaf spring has a pressing portion to press the end of the lock pin against the bottom of the cam groove, and movable contacts for contacting to and being separated from the associated fixed contacts of the terminals in accordance with the movement of the slider. The fixed contacts are electrically connected to one another via the movable contacts touching the fixed contacts.
