98W66 - ESAB SPDT Push Button Switch 10A 125V

Technical Overview of the ESAB 98W66 Switch

The ESAB 98W66 is a high-quality electromechanical component designed to serve as a reliable replacement switch for compatible ESAB welding power sources and industrial equipment. Engineered to meet the rigorous demands of the welding environment, this switch features a Single Pole Double Throw (SPDT) configuration. This allows the component to control two distinct circuits with a single input, providing versatility in control logic, whether used for power activation, mode selection, or trigger mechanisms.

Electrically, the unit is rated for a maximum current of 10 Amperes at 125 Volts AC. This robust rating ensures it can handle the control currents typically found in welding machine command circuits without overheating or contact degradation. The internal contact mechanism is built to resist arcing and wear, extending the service life of the switch even under frequent actuation. The actuation method is a standard push-button interface, providing tactile feedback to the operator to confirm engagement.

Installation is facilitated by standard spade terminals (SPD), which allow for quick disconnect and reconnect operations during maintenance. This design minimizes downtime during repairs, as technicians can easily slide on standard crimp connectors without the need for soldering in the field. The physical housing is constructed from durable materials capable of withstanding the thermal and mechanical stresses common in shop environments. As a genuine ESAB part, the 98W66 ensures dimensional accuracy and electrical compatibility with original equipment specifications, eliminating the risks associated with generic aftermarket replacements.

This component is critical for restoring full functionality to control panels that have suffered from switch failure due to mechanical fatigue or electrical overload. By utilizing the correct OEM specification, maintenance personnel ensure the continued safety and reliability of the welding apparatus.
