visibility red emergency stop mushroom push button, model XB2BS542C. Designed to provide a clear, immediate means to stop machinery and control circuits when a dangerous condition occurs. The large mushroom head is easy to find and press in an emergency, and the turntorelease mechanism gives a simple, deliberate way to reset the device. Key benefits Fast, reliable shutdown: The pushtoactuate emergency stop opens the 1 N/C (one normally closed) contact to interrupt the control circuit quickly and safely. Positive reset action: Turntorelease design prevents accidental reactivation; equipment remains stopped until the operator deliberately twists the button to reset. Clear visibility and ergonomics: Red mushroom actuator provides an unmistakable visual cue and a large surface area for quick access under stress. Product highlights Model: XB2BS542C Function: Emergency stop push button, turntorelease reset Contact configuration: 1 N/C (one normally closed contact) Actuator style: Red mushroom head for easy activation Operation: Press to stop (opens N/C contact), twist to release and restore circuit How it solves common problems Reduces response time in emergencies by providing a single, easytolocate control to stop equipment immediately. Prevents unintended restart after an emergency stop through the twisttorelease mechanism, improving operator safety. Simplifies wiring for stop functions with a single normally closed contact designed for breaking control circuits. Typical applications Industrial machinery control panels where a quick, reliable emergency stop is required. Conveyor systems and materialhandling lines to provide immediate shutdown in case of jams or hazards. Test benches, machine tools, and robotics cells for operatoraccessible emergency stop control. Usage notes The device uses a normally closed contact so pressing the button opens the circuit. Ensure the contact is wired correctly into the safety or control loop according to your system design. After an emergency stop, twist the mushroom head to release and allow the circuit to be reclosed only when it is safe to restart. Why choose this model XB2BS542C combines an easily identifiable red mushroom actuator with a turntorelease mechanism and a single normally closed contact configuration to provide a straightforward, dependable emergency stop solution for control panels and machinery where clear, deliberate reset behavior is required.
