Abstract

A rocker switch. Including pedestal and button, ejector pin, terminal, metal movable contact spring, wherein the pedestal is a cavity casing that has the panel, and button normal running fits the pedestal and opens the oral area, and the terminal is two or more, and there is the metal contact on the top of each terminal, and its bottom has metal wiring foot, and metal movable contact spring shakes the top of fitting in middle terminal, and ejector pin one end links to each other with the button, the other end and the cooperation of metal movable contact spring contact, and the characteristic is: the inner side of the open part of the seat body is provided with a water tank ring, the water tank ring is positioned below a matching gap between the open part of the seat body and the button, and the water tank ring is provided with a water outlet leading to the outside of the seat body. The utility model discloses the dress is when mesa, the uncovered portion of pedestal up, has water to get into from the gap between uncovered portion and the button on the mesa, just falls back in the basin circle and outside the pedestal of arriving side by side, and can not fall into the internal short circuit that causes between the post group of interior pedestal, has solved the potential safety hazard problem.

Description

A kind of rocker switch

Affiliated technical field

The utility model belongs to a kind of low-voltage power switch, particularly rocker switch.

Background technology

The present rocker switch that generally uses, structure is a hollow base frame that has panel, the uncovered portion of the pedestal button that has been rotatably assorted, there is a push rod button inboard, be provided with the binding post more than two or two in the pedestal, the top of each binding post has hard contact, its bottom to have the metal connection pin to stretch out outside the pedestal, and the top of the binding post that one of them mediates is shaken and is combined with a metal movable contact spring, push rod and metal movable contact spring contact matching.The defective of this rocker switch is: when switch was contained on the table top, there was very big hidden danger in fail safe, because the uncovered portion of pedestal up, entered in the pedestal from the slit between uncovered and the button easily when on the table top water being arranged, and caused short circuit between the binding post.

Summary of the invention

Intake, exist the defective of potential safety hazard up the time easily in order to overcome the existing uncovered portion of rocker switch, the utility model provides a kind of improved rocker switch, can overcome the prior art defective.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of rocker switch, comprise pedestal and the button that is mounted thereon, push rod, binding post, the metal movable contact spring, wherein pedestal is one to have the hollow housing of panel, button is rotatably assorted in the uncovered portion of pedestal with regard to pin joint in the middle of it, binding post is more than two or two, there is hard contact on the top of each binding post, the bottom of each binding post has the metal connection pin to stretch out outside the pedestal, the metal movable contact spring shakes the top that is matched with a binding post that mediates, push rod one end links to each other with button is inboard, its other end and metal movable contact spring contact matching, it is characterized in that: uncovered inboard of pedestal is provided with a tank circle, what the tank circle was in uncovered of pedestal and button cooperates the below, slit, and the tank circle has discharge outlet to lead to outside the pedestal.

Above-mentioned tank circle be in uncovered of pedestal and button to cooperate the below, slit be to be contained in table top, the uncovered portion of pedestal user mode up by rocker switch.

Above-mentioned rocker switch can be circular switch, oval switch or square switch etc.Above-mentioned push rod can be got various suitable concrete structures.

The beneficial effects of the utility model are: since uncovered of pedestal and button cooperate the slit below be provided with the tank circle, the tank circle has discharge outlet to lead to outside the pedestal, when rocker switch is contained in table top, the uncovered portion of pedestal up the time, there is water to enter on the table top from the slit between uncovered and the button, just fall after rise in the tank circle and be discharged to outside the pedestal, and can not fall in the inner base frame, because of causing the potential safety hazard of short circuit between the binding post group, water inlet just is resolved.
