Description

Technical Field

[0001] The utility model belongs to the field of switches, and particularly relates to a rocker switch. Background Art

[0002] The three-position illuminated rocker switch is an electrical switch with three control positions and a built-in indicator light, and is usually used in electronic devices. Its structure includes: a housing, a position button provided at the upper end of the housing, an intermediate terminal provided in the middle of the bottom of the housing, and side terminal pins provided on both sides of the bottom of the housing. A rocker is provided at the top of the intermediate terminal, and a conductive slider is provided at the bottom of the position button and abuts against the rocker. Usually, when the position button swings left or right, the moving contact at the end of the rocker contacts the static contact at the top of the side terminal pin to form a circuit; when the position button is in the middle position, the moving contact at the end of the rocker separates from the static contact at the top of the side terminal pin to form an open circuit. The disadvantages are: in the open circuit state, the positioning effect of the intermediate terminal on the rocker and the rocker on the conductive slider is poor, which easily leads to accidental closing of the switch.
