An air switch helps convert pneumatic button input into electrical switching action, and this Herga Electric version is a threaded momentary SPDT model with a center spout using the 6871-OCO-U126 reference. Momentary air switches are useful because they return to their original state when the pneumatic input ends, making them appropriate for specific pulse-style control functions.This part has practical value because the center-spout arrangement and momentary SPDT format help preserve the original connection and response behavior of the supported control system. A properly selected Herga switch contributes to more dependable actuation and more accurate restoration of the intended control action.This type of part is especially useful when the original switch no longer responds correctly to air pressure or no longer returns properly after activation. That helps restore the intended control behavior without replacing the broader pneumatic interface.Installed in the proper application, this air switch helps support dependable momentary control and more confident long-term operation. Threaded momentary SPDT air switch from Herga Electric Features a center-spout configuration for compatible installations Helps convert pneumatic input into momentary switching action Useful when replacing a failed or unreliable original switch Improves control response and replacement confidence
