Push switch

A push switch comprising:

• a housing;
• a button slidably connected to the housing and comprising a protrusion protruding therefrom;
• a first elastic member positioned between the housing and the button to apply a rebounding force to the button;
• and
• a securing member comprising a rotating block and a second elastic member, the rotating block rotatably connected to the housing and arranged on one side of the protrusion, one end of the rotating block defining a recess, the second elastic member being connected to the housing and the rotating block to apply a rebounding force to the rotating block;
• wherein the protrusion drives the rotating block to rotate when the button is pushed by an external force, the first elastic member is compressed, and the second elastic member is deformed;
• after the external force has ceased, the button starts to move back by the rebounding force of the first elastic member, the rotating block moves back by the rebounding force of the second elastic member, the button keeps in the predetermined position when the button moves such that the protrusion is retained in the recess;
• the protrusion of the button disengages from the rotating block when the button is driven again by the external force, after the external force has ceased, the rotating block rotates to an initial position by the rebounding force of the second elastic member, the button moves back to its initial position by the rebounding force of the first elastic member.
