634516 - ESAB SPDT Toggle Switch 10A 250V Replacement

Industrial Grade Electromechanical Control

The ESAB 634516 is a precision-engineered Single Pole Double Throw (SPDT) toggle switch designed to meet the rigorous demands of industrial welding equipment. In the realm of machine maintenance and repair, component reliability is paramount. This switch is rated for a substantial 10 Amperes at 250 Volts, making it capable of handling the control circuits found in heavy-duty power sources and wire feeders without succumbing to arcing or premature contact failure. The SPDT configuration allows for versatile circuit management, enabling the switch to control two separate output circuits from a single input, or simply function as a robust on/off controller depending on the wiring schematic of the specific machine.

Technicians will appreciate the inclusion of Quick Disconnect (Q/D) terminals. These spade-style connectors significantly reduce downtime during repair procedures by eliminating the need for soldering in tight chassis spaces. The terminals provide a secure, vibration-resistant mechanical and electrical bond, which is critical in welding environments where equipment is frequently moved or subjected to high-frequency vibrations. The toggle mechanism itself offers a tactile, positive 'click' engagement, ensuring the operator knows exactly when the state has changed, preventing accidental mode switching.

When sourcing replacement parts for ESAB equipment, utilizing the correct OEM specification is vital for maintaining the UL/CSA listing of the machine. Generic switches may physically fit into the panel cutout but often lack the dielectric strength or thermal endurance required for the internal operating temperatures of a welding power source. The 634516 is built to withstand these conditions, ensuring long-term operational stability and safety for both the machine and the operator.
