ABSTRACT:
A temperature responsive switch having a bimetal disc disposed within a recess in the switch body is provided with a guide member having a hole extending therethrough and a sperical shaped transmitting member disposed in the hole in contact with the bimetal disc. A leaf spring is secured to the body at one end thereof in overlying relation to the hole in engagement with the spherical shaped transmitting member. A moveable contact is fixed to the other end of the leaf spring and a stationary contact is provided on the body adjacent the moveable contact. A spring normally disposed between the body and the leaf spring biases the leaf spring in a direction to separate the contacts and upon over center movement of the bimetal disc the spherical shaped transmitting member will move the leaf spring against the force of the spring to bring the contacts into engagement with each other.
