The Tecmark latching air switch in DPNO format is designed for compatible threaded pneumatic control applications that require a maintained-state switching action. Latching switches are useful because they allow the system to change state with a brief air input and then remain in that changed condition until the next actuation.

This replacement is especially useful when the original switch has become unreliable, no longer latches correctly, or has failed internally. The threaded body helps preserve the original mounting style in applications built around a threaded air switch format.

It is a practical service option when restoring dependable maintained-state switching and correct physical fit are both important to the repair.

  • Tecmark latching air switch in DPNO format
  • 20 amp rated with threaded body design
