Description

Panel switch

Technical Field

Embodiments of the present disclosure relate generally to the field of electrical equipment technology, and more particularly, to a panel switch.

Background

The panel switch can conveniently control the electric equipment and the power circuit to be connected or disconnected. The conventional panel switch is generally provided with an indicator lamp, and whether the electric equipment is connected with the power circuit or not is judged through the extinction or the lighting state of the indicator lamp.

The pressing plate 9 is provided at an end of the cover plate 3 remote from the base 1.

Note that, since the second circuit board 42 is thin, the second circuit board 42 is not shown in fig. 2. As shown in fig. 2, the second circuit board 42 should be disposed above the insulating board 6.

In some embodiments, fig. 4 illustrates a schematic structural view of the panel switch 100 along another viewing angle according to that shown in fig. 2. As shown in fig. 3 to 4, a first wire inlet end 11, a first wire outlet end 12, a second wire inlet end 13 and a second wire outlet end 14 are arranged on the side of the base 1 facing away from the cover plate 3.
