Abstract
A vandal-resistant push button switch assembly. The switch assembly has a switch actuating device with no exposed fasteners which switch may be used in a prison cell or other area requiring a high degree of vandal resistance. Although the switch may be readily operated from within the cell, it cannot be removed from the cell or destroyed under anything but the most extreme conditions. The switch has a push button actuating shaft which is depressed by the user and this shaft in turn activates a push button electrical switch mounted on the back side of the mounting surface.
