Description

Technical Field

[0001] This utility model belongs to the field of switches, and in particular relates to a metal toggle switch. Background Technology

[0002] A metal toggle switch is an electronic component that controls the on / off state of a circuit by manually moving a lever (metal rod). The traditional structure of a metal toggle switch includes: a base, a metal housing outside the base, a center pin and side pins at the lower end of the base, a rocker arm mounted on the center pin, and an actuating assembly at the upper end of the base. A moving contact is located on the rocker arm, and a stationary contact on the side pins engages with the moving contact. A sliding assembly rests against the rocker arm at the lower end of the actuating assembly. 1. The lever base and decorative cover of the actuating assembly are usually glued together, making assembly cumbersome and prone to loosening and detachment; 2. This results in poor circuit performance. Utility Model Content

The metal shell is provided with a positioning boss at the upper end that engages with the positioning recess. The base is provided with a positioning post at the upper end that is interference-fitted with the first positioning groove.

[0005] The actuation assembly also includes a decorative cover. The end face of the lever seat has a groove and a slot in the center hole. The lower end of the decorative cover has a locking post that connects to the slot.

[0006] The upper end of the base is provided with a conical sealing element via a gasket. The gasket has alternating outer positioning protrusions and inner positioning protrusions. The lower end of the lever is provided with an annular sealing groove. The upper end of the base is provided with a second positioning groove that positions and cooperates with the outer positioning protrusions. The lower end of the conical sealing element is integrally formed with a sealing gasket that fits against the top of the base and the gasket, and the upper end is integrally formed with a sealing ring that seals and cooperates with the annular sealing groove.

[0007] The lower end of the lever is provided with a sliding member that abuts against the rocker plate. The sliding member includes a bushing and a spring and a sliding sleeve arranged sequentially in the bushing. The side wall of the bushing is provided with an annular retaining rib that is interference-fitted with the mounting cavity of the lever.

[0008] The base is provided with a rib to prevent misalignment on one side.
