Senays Pool Air Switches

Overview

The SENAYS trm111a is a TinyTrol pneumatic air switch configured as a single pole double throw (SPDT) momentary switch rated at 21 amps. Momentary operation means the switch returns to its neutral position immediately after the actuating air pulse is released, making it well suited for hands-free activation in wet environments. Licensed HVAC, plumbing, and pool service technicians install this type of air switch where a remote pushbutton or air hose generates the switching signal rather than direct electrical contact. The durable construction is intended to withstand repeated cycling and moisture exposure in both residential and commercial installations. The trm111a is designed for air-activated control applications in pools, spas, and baths. Typical installations include whirlpool tubs, jetted spas, and pool equipment pads where the control button is mounted at the water's edge and a small-diameter air tubing run connects it to the switch body located at the equipment. The momentary SPDT configuration allows the switch to trigger pumps, blowers, or other loads without the operator ever touching an energized component. It is appropriate for both residential and light commercial environments that require reliable, low-maintenance switching.
