Description
Technical field
The present invention relates to a kind of rocker switch, especially relate to a kind of two-way and force to disconnect rocker switch.
Background technology
For using rocker switch as the equipment of mains switch in big current inductive load, power tool load and capacity load, because inductive load and power tool load equipment can produce the impulse current of an about rated current 6 times when starting, and capacity load has discharge impact electric current, and (impulse current is relevant with capacitance, be directly proportional), produce arcing, high temperature; When immediate current is very large, there will be the dynamic point of switch and dead point is sintered together phenomenon, make switch cisco unity malfunction, when closedown external power supply, after the decline of switch internal temperature, switch can work again, but also there will be silver point sintering phenomenon during follow-up work.
Summary of the invention
Object of the present invention is exactly provide a kind of safe and reliable to overcome defect that above-mentioned prior art exists, a pole can be prevented to lose efficacy and the two-way that causes the accident is forced to disconnect rocker switch.
Object of the present invention can be achieved through the following technical solutions:
A kind of two-way is forced to disconnect rocker switch, comprise button, shell, rotation axis, force bar, movable contact spring, moving contact, fixed contact, limit contact feet, middle contact feet and base, described button is located at the top of shell, described base is located at the bottom of shell, described pressure bar upper end and button clamping, force to be provided with rotation axis in the middle part of bar, described movable contact spring is connected to the below of button, movable contact spring is provided with moving contact, described fixed contact is corresponding with moving contact to be connected, described limit contact feet and middle contact feet are through base, limit contact feet is located at the outside of fixed contact, middle contact feet is located at the below of movable contact spring.
Described button is made up of pressure button cover and push-button socket, and push-button socket is located in pressure button cover, and pressure button cover can be planar shaped, V face shape, arc surfaced, some light arc surfaced or waterproof arc surfaced structure.
The bottom of described push-button socket can arrange luminous element.
The below of described push-button socket arranges a boss, offers through hole in boss, arranges spring in this through hole, and this spring is located in the through hole that arranges below push-button socket, and with push-button socket clamping above spring, the bottom in through hole is provided with slide cartridge or steel ball.
Described slide cartridge or steel ball abut with the movable contact spring of below.
Described boss closely cooperates with forcing bar.
Described pressure bar and movable contact spring are matched in clearance.
Power is applied to pressure button cover, drive push-button socket, boss on push-button socket and pressure bar closely cooperate, when push-button socket rotates, force bar also to rotate, after rotating certain angle thereupon, bar is forced to start to touch movable contact spring, when silver point clings, movable contact spring can be promoted by force, thus silver point is disconnected completely.
Compared with prior art, the present invention is safe and reliable, disconnects with bipolar pressure, live wire and zero line (or electrode line and negative line) is disconnected simultaneously, causes the accident to prevent a pole to lose efficacy.
