Abstract
An electronic lock with manual combination override for opening of a lock by both an electronic and manual means. The electronic lock has a bolt operating release mechanism which operates to allow opening of the lock by either the electronic or manual mode. The electronic and manual modes both operably open the lock through operation of the bolt operating release mechanism. The bolt operating release mechanism is a multi-component assembly operable as a unit or relative to each component dependent on the mode of operation. The electronic mode is operably by use of electronic components which include but are not limited to, pressure-sensitive switches, logic circuit, and a circuit mounting board. An electronic combination is generated, retained and operable with the electronic components to open the lock.
