PresAir Trol Tinytrol Momentary Air Switch [DPDT] [Threaded] [Center Spout] (TVM-211A) haywardpool 1/2 inch by 1 inchThe PresAir Trol TinyTrol momentary air switch in DPDT format is intended for compatible threaded applications that require a center spout layout and a quick return double pole switching response. In pneumatic systems like these, the switch must respond cleanly to a brief air pulse and then return as intended. This replacement is especially valuable when the original switch no longer returns reliably, feels inconsistent, or has failed internally.
