Abstract:
1. A system for releasing an electromagnetic lock upon detecting a proximity of a person or object, comprising: a) a touch bar assembly including a touch bar and bracket wherein said touch bar is movably connected to said bracket; b) at least one micro-switch configured for detecting movement between said touch bar and bracket; c) a first capacitive circuitry connected to said touch bar and configured to detect said proximity and to release said electromagnetic lock upon such proximity detection; d) a second circuitry integral with said first capacitive circuitry configured to release said electromagnetic lock upon a detected movement of said touch bar in relation to said bracket through a certain travel; and e) a Dual N and P Channel Power MOS-FET connected to said at least one micro-switch for filtering out mechanical noise subjected upon said at least one micro-switch.
