Adjustable safety switch

Abstract

A switch device includes a body with a switch member pivotably engaged with a top opening of the body and a first terminal and a second terminal respectively extend through two slots in a bottom of the body. A first contact point is connected to the second terminal. A bi-metallic plate has a first end fixed to the first terminal and a second contact point is connected to an underside of a second end of the bimetallic plate. The second contact point is located above the first contact point. A link has an upper end pivotably connected to the switch member and a lower end of the link clamps the second end of the bimetallic plate. A connection member is fixedly connected to an inside of the body and an adjusting member movably extends through a wall of the body and contacts the connection member. A U-shaped biasing member has a first end connected to the second end of the bimetallic plate and a second end of the biasing member is connected to the connection member. The biasing member provides the bimetallic plate proper flexibility so as to ensure the deformation of the bimetallic plate when overload.
