Abstract
A controlled plumbing fixture comprises a plumbing fixture, an electromechanical valve operably associated with the fixture for regulating water flow thereto, a control operably associated with the valve for controlling operation thereof, and a push button assembly cooperating with the control. The push button has an axially movable plunger, an axially movable signal supplying element, and an elastomeric member disposed about and slidably engaged with the signal supplying element for selectively positioning and maintaining the signal supplying element intermediate axially spaced first and second points. The push button is operably associated with the control for causing a demand signal to be supplied to the control for thereby causing the control to supply a control signal to the valve, so that operation thereof occurs upon actuation of said signal supplying element by movement of the plunger.
