TBS132A Air Switch: The Heart of Your Hot Tub’s Safety System

As an experienced hot tub parts supplier, I’m excited to introduce you to the TBS132A pressure switch – a crucial component for ensuring the safety and efficiency of your hot tub or spa system. This high-quality switch, manufactured by the reputable Tecmark, is designed to keep your hot tub running smoothly and safely.

Product Overview

The TBS132A is a Single Pole Normally Open (SPNO) air switch with a 16amp capacity. It features a durable EPDM diaphragm, making it ideal for use in hot tub and spa environments. This switch plays a vital role in your hot tub’s operation by detecting water flow and preventing potentially dangerous situations.

Key Features

Safety First

The primary function of the TBS132A is to detect sufficient water flow, ensuring it’s safe for your heater to operate. This feature is crucial in preventing damage to your heater and maintaining the overall health of your hot tub system.

Dry Run Protection

Another essential feature of this switch is its ability to prevent your pump from running dry. This protection can significantly extend the life of your pump and save you from costly repairs down the line.

Versatile Application

While primarily designed for hot tubs and spas, the TBS132A can be used in various applications where pressure detection is required. Its compact size and reliable performance make it a go-to choice for many water-based systems.

Installation and Compatibility

The TBS132A is designed for easy installation, fitting into a 15mm hole. Its compact dimensions (48mm x 25mm x 48mm) make it suitable for various setups, even in tight spaces.

This switch is commonly used in bath or jetted tub applications, often in conjunction with a TBS133 momentary/alternate air control switch. The combination of these switches creates a robust control system for your hot tub or spa.

How It Works

Instead of using a dry air pipe connected to an air transmitter, the TBS132A connects to a pressurized outlet of the pump or heater. The water pressure lifts the EPDM diaphragm, completing the circuit. This design ensures accurate pressure detection and reliable operation.

Once the switch detects sufficient pressure, it completes the circuit with the TBS133 until either the alternate switch is turned off or the pressure in the pipework drops, indicating a low flow situation.

Durability and Longevity

The TBS132A is built to last. Its EPDM diaphragm is specially chosen for its resilience in hot tub environments, resisting degradation from chemicals and heat. This durability ensures that your switch will continue to perform reliably for years to come.

Conclusion

The TBS132A pressure switch is more than just a component – it’s a guardian for your hot tub system. By ensuring proper water flow and preventing dry runs, it protects your investment and enhances your hot tub experience. Whether you’re replacing an old switch or upgrading your system, the TBS132A is an excellent choice for any hot tub enthusiast or professional.

Remember, proper installation and regular maintenance are key to getting the most out of your TBS132A switch. If you have any questions about integration or compatibility with your specific system, don’t hesitate to reach out. Your safety and satisfaction are my top priorities.
