VMS stocks manual push buttons, piezoelectric push buttons and hydraulic push buttons for installation on stainless steel prison fixtures and other locations where extreme vandalism is a concern. If a front access panel is not provided, these buttons require access behind the wall for installation and servicing. 
Push button actuators for prison hydraulic valves use air to power the valve and these operators to meet ADA accessibility requirements.  Piezo switches operate according to the “piezoelectric effect” whereby mechanical pressure, such as the pressure of a finger, generates a voltage that opens or closes a circuit. Piezo switch technology provides vandal-resistant lavatory, shower, and flush valve actuation, eliminating chrome-plated pushbuttons and their associated problems.
VMS stocks a wide variety of push buttons and parts from these trusted correctional suppliers; Acorn, Bradley, I-CON, Kohler, Metcraft, Sloan, Willoughby and others.
