Electrical rotary switch
First Claim
1. An electrical rotary switch comprising a casing having front and rear ends, a rotary operating member mounted for rotation about an axis extending between said front and rear ends, said operating member being manually operable from a position on said axis at said front end, a first elongated and flexible contact member having an axis of elongation parallel to said axis mounted for movement in opposed directions along a path transverse to but not intersecting the axis, between a first position in which a first contact surface of the first contact member is in electrical contact with a second contact surface of a respective second contact member and a second position in which the contact surfaces are not in electrical contact, the path being approximately normal to the contact surfaces, and the operating member having an abutment surface movable in said opposed directions as the operating member rotates to impart movement to the first contact member in one or both directions.

Abstract
An electrical rotary switch is disclosed having a rotary operating member (16) mounted for rotation about an axis. A first contact member (32) is mounted for movement in opposed directions along a path transverse to but not intersecting the axis, between a first position in which a contact surface (38) of the first contact member (32) is in electrical contact with a contact surface (42) of a respective second contact member (36) and a second position in which the contact surfaces are not in electrical contact. The path is approximately normal to the contact surfaces, and the operating member has a surface (44) to impart movement to the first contact member in one or both directions.
