BWSVTSW1F - Universal Flat Momentary TIG Torch Switch

Technical Overview of the SW1F Momentary Switch

The SW1F Momentary Flat Switch is a specialized electromechanical component designed for the remote actuation of welding power sources, specifically within TIG (GTAW) and Plasma Cutting (PAC) applications. As a momentary Single Pole Single Throw (SPST) switch, it maintains an open circuit in its resting state and closes the circuit only when pressure is applied, providing the operator with precise, on-demand control over the arc initiation and termination sequence.

Engineered with a low-profile, flat form factor, this switch is intended to be mounted directly onto the handle of a welding torch. The flat design is critical for ergonomics, allowing the welder to maintain a steady grip and precise torch manipulation without the obstruction or hand strain often associated with bulky, protruding buttons. This profile ensures that the switch can be secured using tape, zip ties, or integrated handle slots, making it a truly universal solution for aftermarket repairs and custom torch setups.

Electrically, the SW1F features a simple 2-wire interface, facilitating straightforward integration into existing control cables. It is compatible with standard low-voltage control circuits used by major welding machine manufacturers (such as Miller, Lincoln, and ESAB) to trigger the contactor or gas solenoid. The switch mechanism is built to endure the repetitive cycling inherent in tack welding and production fabrication environments, ensuring reliable contact closure and minimizing signal bounce.

This component is an essential spare for maintenance, repair, and operations (MRO) inventories, providing a quick and effective remedy for failed torch triggers. Its compatibility extends across air-cooled and water-cooled torch models, making it a versatile addition to any welding technician's toolkit.
