The PresAir Trol TinyTrol DPDT momentary air switch is built for compatible pneumatic control systems that require a momentary double-pole double-throw switching response. In these systems, the switch must react cleanly to a brief air pulse and then return as designed.This model is especially valuable when the original air switch has become inconsistent or no longer returns and switches correctly during use. Installing the proper momentary replacement can help restore the intended behavior without changing the rest of the control arrangement.It is a smart service solution when the system depends on quick, non-latching actuation at the air-switch level. PresAir Trol TinyTrol DPDT momentary air switch Helps restore quick-return pneumatic switching in compatible systems Useful when the original switch has failed or become erratic Supports original control-system logic and response Improves service confidence and control consistency
