Described pressure button cover can be planar shaped, V face shape, arc surfaced, some light arc surfaced or waterproof arc surfaced structure.
In the described pressure button cover luminous element can also be set.
Described movable contact spring parts comprise movable contact spring and moving contact, are connected with stage clip on the described movable contact spring, and described moving contact is connected the one or both sides of movable contact spring.
Described case member comprises edge joint haptic element, fixed contact and middle contact feet, and described middle contact feet is located at the middle part of casing assembly bottom surface, the one or both sides of contact feet during described edge joint haptic element is located at, and described fixed contact is connected with the moving contact contact.
Described case member also comprises lamp base, resistance spring and resistance, and this lamp base is located at the side at middle contact feet, and described resistance spring and resistance are located in the shell, and resistance is located at a side of movable contact spring parts, and described resistance Spring Card is located on the resistance.
Compared with prior art, the utlity model has following advantage:
One, the scope of application is wide: rocker switch in the market all is to adopt lever principle; For little electric current≤4A (non-resistive load), or more satisfactory structure, but for electric current 4A＜I (non-resistive load); Still can occur to break off phenomenon behind the silver point sintering; After this improved, the dissatisfied fully silver point sintering of determining can not break off phenomenon, makes switch play the operate as normal effect
Two, safe and reliable: as to force disconnection can effectively prevent to combine to cause equipment fault and security incident in the utility model because of the contact.
