Description

Technical Field

[0001] The utility model relates to a boat-shaped switch. Background Art

[0002] The rocker switch is also called a seesaw switch because it looks like a boat. It is often used as a power switch for electronic devices. The rocker switch usually includes a shell, a cavity is provided on the shell, a rocker key rotates in the cavity, and a static contact foot assembly and a moving contact piece assembly are arranged in the shell. By pressing the rocker key, the moving contact piece assembly is connected to the static contact foot assembly, thereby controlling the conduction of different pin circuits. The existing rocker switch has the following defects: 1. There is a gap between the rocker key and the shell, and external water can easily enter the shell through the gap, and the waterproof performance is poor, thereby affecting the normal operation of the static contact foot assembly and the moving contact piece assembly in the cavity; 2. When the rocker key is pressed, due to the gap and positioning problems, there is an unstable swing and inaccurate and unreliable movement, so it needs further improvement. Utility Model Content
