ABSTRACT:
An improved rotary-type selector switch for fan speed control or the like including curved terminal members supported upon a base member around a central boss extending therefrom and having a conductive contactor for selectively interconnecting said terminal members when said contactor is pivoted. A cover member is attached to the contactor for pivotal movement together and retains springs which push the contactor against the terminal members and permit movement of the cover toward the contactor. The aforedescribed parts are assembled by a pin fastener with an expandable first end portion which engages the base in snapfitting relation and an enlarged second end portion overlying the cover member. Circumferentially spaced detent means and a projecting ridge formed between the pin fastener and the cover operably engage one another positively to locate the cover and connected contactor in a plurality of annular positions with respect to the base member.
