Tecmark Air Switch TBS125 – DPDT 16 Amp (Alternate Action)
Pneumatic air-actuated switch for spa control systems
The TBS125 is a high‑quality remote pressure switch (air switch) designed for spas, whirlpools, or hot tubs. Manufactured by Tecmark, it provides double-pole, double-throw (DPDT) switching so you can simultaneously control two separate circuits (e.g., pump speeds, indicator light). It features alternate action—meaning each actuation toggles the output between two stable positions.

Key Features
-
Dual Circuit Switching
Both poles switch simultaneously—useful for controlling multiple devices or modes with one air button. -
Self-Latching Action
Pressing the air button toggles the switch and it stays in its new state until pressed again. -
Robust Electrical Ratings
Suitable for switching resistive loads up to 16 A and inductive loads up to 4 A (e.g., pump motors up to ~1 HP). -
Compact and Serviceable Design
Equipped with six spade terminals for direct accessory wiring; fits within typical spa control boxes. Ideal for retrofit or custom installations. -
Reliable OEM Part
Built to Tecmark’s high standards—widely used in spa systems requiring manual mode switching or relay logic.
Typical Applications
-
Switching between low and high-speed pump modes
