ZB2BC31 NO Normally Open Green Sign Mushroom Momentary Push Button Switch is a straightforward, reliable operator designed for clear, intentional control in industrial and commercial panels. Its large green mushroom head and momentary, normally open action make it ideal where a visible, easytopress control is needed for temporary commands such as start, acknowledge, or test functions. Key benefits Clear, visible control: the green mushroom head provides an unmistakable operator target and status cue, reducing operator error. Simple momentary action: as a normally open (NO) momentary switch, the circuit only closes while the button is pressed — useful for pushtotest, momentary start, or acknowledgement functions. Reduces accidental latching: the spring momentary design avoids unintended sustained operation and makes it easy to implement pulsetype controls. Suitable for frequent use: designed for repeated operator actuation where quick, positive response is required. Key attributes Model: ZB2BC31 Contact type: NO (Normally Open) Action: Momentary (spring ) Head style: Mushroom (largediameter operator) Color/sign: Green Function: Push button switch for momentary closure How it works (clear explanation) Normally open (NO) contact: the switch circuit is open at rest and closes only while the button is depressed. Momentary operation: releasing the button immediately returns it to the open state, making it suitable for pulse or temporary commands. Typical applications / use cases Machine start control: use as a manual momentary start button on production equipment or conveyors where the operator must hold or briefly press to initiate an action. Alarm or fault acknowledgement: provide a clear, intentional pushtoacknowledge control on operator panels to silence alarms or acknowledge warnings without latching. Test or jog functions: operate test sequences, jog motors, or momentary actuators where temporary contact is required. Installation and operation notes Intended as a push button operator for panel use; ensure correct wiring consistent with a normally open contact when integrating into control circuits. Because it is a momentary NO device, it is ideal where temporary contact is required rather than a maintained on/off function. Why choose this switch The ZB2BC31 combines a visible mushroomstyle operator with a simple, reliable momentary NO contact. It provides unambiguous operator feedback and predictable functionality for common control tasks in industrial and commercial environments.
