The Highpower Model 700 key switch is a heavy-duty, mortise cylinder type assembly used for general purpose key-controlled switching applications. It can be used as a simple door access control device or can be used as a lockout device for machine controls. Standard features include two bi-color LEDs, used as indicators, and an integrated set of tamper switches. Tamper switches are used to monitor if the key switch assembly has been removed from the electrical box that it's installed in.
