Tecmark TBS317 Dpdt 20A Latching Air Switch

Product Description

The TECMARK TBS317 is a Double Pole Double Throw (DPDT) latching air switch rated for 20 amps. It converts a pneumatic pulse from a push button into an electrical switching action, making it a common control component in spa, hot tub, and pool equipment panels. The switch mounts through a 9/16-inch panel hole and connects to an air tube via a 1/8-inch barb fitting. Metal construction supports durability in wet-area control enclosures. Licensed electricians and pool service technicians are the typical installers for this type of control component.

The TBS317 is suited for residential and light commercial spa and pool applications where air-activated switching is required. Its latching design means the circuit stays in its last switched state without continuous air pressure, which is standard for spa jet and blower on/off control circuits. The 20-amp rating accommodates motor loads typical of spa pump and blower systems.

Key Features

• DPDT latching configuration switches two independent circuits simultaneously with a single air pulse
• 20-amp rating supports spa pump and blower motor loads
• 9/16-inch panel mount hole for standard spa topside or equipment panel installation
• 1/8-inch barb air tube connection for direct push-button air line attachment
• Metal construction for durability in wet-environment control enclosures

Compatibility

Designed as an OEM-style replacement air switch for residential and light commercial spa, hot tub, and pool equipment control panels requiring a DPDT latching configuration.

Installation Notes

Installation should be performed by a licensed electrician or qualified pool and spa service technician in accordance with applicable NEC and local codes. Disconnect and lock out all power to the equipment panel before removing or installing the switch. Route the air tube from the push button to the 1/8-inch barb fitting, ensuring no kinks or moisture traps in the line. Verify that the load current does not exceed the 20-amp rating of the switch before energizing.
