Abstract
An electromagnetic door lock and release mechanism is disclosed in which the electromagnet is contained within a separate sub-assembly which is electrically connected to the control circuitry by quick connect type of frictional contacts. Accordingly, the electromagnet portion of the system may be changed without requiring the maintenance person to have access to the wires that connect the electromagnetic door lock and release mechanism to its control circuitry. This advantageously permits replacement of the electromagnet without requiring the services of an electrician.
