Abstract
A contact assembly for use in an electrical apparatus comprises a housing and a pusher movably mounted in the housing. A movable contact is supported on the pusher. A stationary contact is proximate the moveable contact in the housing. A return spring biases the pusher to a normal position. A contact spring operatively associated with the moveable contact forces the movable contact against a stop associated with the pusher. The contact spring and the return spring are of identical construction and are positioned in the housing so that force or torque produced by the return spring is greater than force or torque produced by the contact spring.
