The LiftMaster 30-22CBNO Contact Plate, NO is a genuine replacement normally open contact block used in LiftMaster commercial door and gate operator control stations. Designed to restore or add a normally open circuit to a pushbutton or key switch assembly, this component closes the control circuit when the associated actuator is pressed, enabling functions such as open, close, or auxiliary commands as specified by the operator’s wiring logic. It is intended for use in LiftMaster control enclosures that accept modular contact blocks and is suitable for service and maintenance on commercial and industrial door operators as well as compatible gate operator stations.
This normally open contact plate installs behind the operator’s button or selector and connects to the operator’s control terminals per the equipment manual; no programming is required. Use where a NO contact is specified by the control logic, and pair with a normally closed contact plate when the station requires both types for stop or safety inputs. For safety, disconnect power before servicing and verify the correct contact type for each function in the LiftMaster operator documentation. Ideal for technicians seeking an OEM LiftMaster replacement part, the 30-22CBNO helps ensure reliable control-station operation in commercial and residential applications that use LiftMaster-branded modular pushbutton stations.
