Key switches are installed in secure locations outside wired, in parallel or series with the power supply
and the electromagnetic lock. If the electromagnetic lock cannot be opened due to failure of the proximity
reader or other incidents, the user can switch between normally closed (N.C.) and normally open (N.O.)
contacts by the key, forcing the door to open. This acts as a backup to access control systems.
