An air switch helps convert pneumatic button input into electrical switching action in a compatible control system, and this Herga Electric version is a 3-function DPDT model rated at 20 amps with a 1/2 inch MPT connection using the 6872-DGO-U126 reference. Air switches are useful because they allow remote pneumatic actuation of electrical functions while keeping the switching hardware away from the user touch point.This part has practical value because the 3-function DPDT configuration supports more complex control behavior than a simpler single-function switch. A properly selected Herga switch helps preserve intended control logic and contributes to more dependable actuation in compatible spa, bath, or pool-related systems.This type of part is especially useful when the original air switch has failed, become unreliable, or can no longer respond correctly to the pneumatic signal from the button assembly. That helps restore system control without redesigning the broader interface.Installed in the proper application, this air switch helps support dependable multi-function control and stronger long-term service confidence. 3-function DPDT air switch from Herga Electric Rated at 20 amps with a 1/2 inch MPT connection Helps convert pneumatic input into compatible electrical switching action Useful when replacing a failed or unreliable original air switch Improves control reliability and replacement confidence Show more
