Switch having a bimetal plate with two legs
First Claim
1. A switch device comprising:
- a switch case having a passage defined through a top of said case and two slots respectively defined in an underside of said case, a button movably received in said passage and a non-conductive plate extending laterally train said button and located in said switch case, a first terminal plate and a second terminal plate respectively engaged with said two slots, said case being composed of a first part having a plurality of recesses defined in a surface of said first part, and a second part having a plurality of rods extending from said second part for engaging with said recesses; and
a bimetal plate having a body and two legs extending from said body, said body connected to said first terminal plate, a conductive member connected between said two legs and said non-conductive plate movably located between said conductive member and said second terminal plate;
wherein each of said first terminal plate and said second terminal plate has a connection hole, and two rivets respectively extend trough said connection holes and engage with two engaging holes defined in said first part.

Abstract
A switch device includes a switch case having a passage in a top thereof so as to receive a button therein. A non-conductive plate extends laterally from the button. A first terminal plate and a second terminal plate respectively extend from the casing. A first contact point extends from a side of the second terminal plate. A bimetal plate is connected to the first terminal plate and has two legs extending therefrom. A conductive member is connected between the two legs and connected to the second terminal plate when the button is pushed. The non-conductive plate is located between the conductive member and the second terminal plate when the button jumps up and the two legs are deformed away from the second terminal plate.
