- wherein the moving contact is installed on the bottom base and a weld leg of the moving contact is extended through the bottom base;
the fixed contact is installed on the bottom base and a weld leg of the fixed contact is extended through the bottom base;
the moving contact and the fixed contact are disposed at opposing positions;
wherein one end of the spring is in contact with the bottom base, and the other end of the spring is in contact with the pressing part;
one opening is defined in the top cover;
the pressing part is extended through the opening of the top cover;
the top cover is assembled to the bottom base;
wherein the moving contact is provided with a first contact surface and two second contact surfaces of arched shape at two sides of the first contact surface;
