ABSTRACT:
A door closer connected to a door panel movable on a door frame has a housing and a rod rotatable with respect to the housing in accordance with the relative position of the door panel and the door frame. The closer includes a rotary switch with limited movement which performs various switching functions dependent upon intended use with the associated electrical components and circuitry. The switch is actuated by a rod extension and also includes a hollow, insulating casing on a housing encompassing the extension with an inwardly projecting stop. An insulating rotor or clutch disc engages the extension with a slip-friction fit. The switch is constructed so it may be adjusted to match a particular door environment.
