Abstract
A push button actuator unit has a housing that defines a passage extending along an axis. A push button assembly has components movable in the passage including a forwardly-biased push button at the front of the housing that is movable along and turnable about the axis. Two independently movable operating elements at the rear of the housing move differently in response to depression of the push button when the push button is turned to different orientations about the axis. The rear operating elements may extend concentrically along the axis, and the unit may be lockable to permit and prevent some operating element movement. The operating elements may be used to selectively disengage, or to engage and move a variety of auxiliary devices situated behind the unit. The unit may provide enhanced resistance to defeat by hammering than has been offered by a known form of push button unit.
