A switch mechanism module for a switch including a first housing member, a second housing member, and an operating mechanism between the first and second housing members. The first housing member has first and second integral stops depending therefrom, and the second housing member has first and second integral legs depending therefrom. The operating mechanism rotates upon rotation of the handle of the switch causing rotation of the rotor of the switch. Movement of the operating mechanism ceases upon engagement of the operator cam with the stop of the first housing member. The integral legs of the second housing member provide reinforcement for the stops to prevent movement of the stops in the direction of the rotating cam.

Modular switch mechanism

A switch assembly for a circuit having an insulating base, a blade, a blade hinge member that allows for rotation of the blade about a pivot position, a first contact member, identical in construction to the blade hinge member, having opposing sidewalls that electrically engage and disengage the blade in response to pivoting movement of the blade, a rotor member for engaging and rotating the blade, and a second contact member, identical in construction to blade hinge member and the first contact member, for retaining a fuse is provided. The opposing sidewalls of the either the blade hinge member or the first and second contact members, being identical in construction, are adapted to either pivotally support the blade, engage and disengage the blade, or secure the fusible member thereto, depending on their position on the insulating base. Identical spring members are connected to the blade hinge member and contact members for retention force. As such, an assembly is provided having identical components for various functions to decrease the number of unique components, decrease cost, and decrease assembly time.
