TBS133 Air Switch: The Heart of Your Hot Tub’s Control System

Introduction

As an experienced hot tub parts supplier, I’m excited to introduce you to the TBS133 Air Switch by Tecmark. This versatile pneumatic switch is a crucial component for many hot tub and spa systems, offering reliable control for your pumps and heaters.

What Makes the TBS133 Special?

The TBS133 is not just any air switch – it’s a precision-engineered device that combines momentary and alternate action functionality. This unique feature allows for seamless operation of your hot tub’s pumps and pressure systems.

Key Features:

• Manufactured by Tecmark, a trusted name in the industry
• Dual functionality: Momentary and Alternate action
• Double Pole, Normally Open (DPNO) configuration
• High power capacity: 16 amp rating
• Versatile applications: Ideal for small pumps and heater combinations

How It Works

When you press and hold your hot tub’s air button or transmitter, the TBS133 springs into action. It closes both the momentary and alternate switches inside, completing the electrical circuit. This allows your pump to run and pressurize the system.

Once the pressure switch (like the TBS132) or vacuum switch (such as the VTBS3002) is engaged, you can release the air button. The pump will continue to run until you either press the air button again or the pressure in the system drops.
