Abstract
A tamper resistant keypad includes one or more key assemblies having a resilient key member and a contact. The resilient key member is configured to flex when the key assembly is depressed to allow the contact to close a key press detection circuit on a circuit board to register a key press. A tamper detection switch assembly at least partially surrounds the resilient key member. The tamper detection switch assembly is configured to detect attempts to access the key assembly.
