Push switch

This creation relates to a switch, and more particularly to a switch that controls the power supply to be turned on and off by a pressing action.

The open relationship is used as a control element for switching power supply on and off, which is common in everyday life. Different from the common use of the seesaw switch, the push-on relationship provides a button for moving the line for the user to press and switch the power.

The pressing stroke of the conventional push switch is relatively short, resulting in poor pressing feel. In addition, the conventional push-type switch has many complicated structures and numerous components, which causes high production cost and increases the burden on the assembly line.

Therefore, how to provide a push-type switch with a good pressing feel and a compact structure is in the direction of the industry's urgent efforts.

The main purpose of this creation is to provide a push-type switch that has a good grip and a compact structure.

To achieve the above object, the push switch of the present invention comprises a housing, a conductive member, a swinging member, a pressing block and an extruded structure.
