Abstract
A push switch includes a housing, a button slidably connected to the housing including a protrusion protruding therefrom, a first elastic member, and a securing member. The securing member includes a rotating block rotatably connected to the housing defining a recess and a second elastic member. The protrusion drives the rotating block to rotate when the button is pushed. After the external force has ceased, the button and the rotating block move back by the rebounding force of elastic members, respectively. The button stays in the predetermined position when the protrusion is retained in the recess. The protrusion disengages from the rotating block when the button is driven again. After the external force has ceased, the rotating block moves to an initial state by the rebounding force of the second elastic member. The button moves to its initial state by the rebounding force of the first elastic member.
