951059 - ESAB Toggle Switch SPDT 3-Position 5A 120V Lug Terminal

Technical Overview of the ESAB 951059 Toggle Switch

The ESAB 951059 is a specialized electromechanical component designed for use within industrial welding power sources and auxiliary equipment. This switch utilizes a toggle actuation mechanism and features a Single Pole Double Throw (SPDT) contact configuration. The SPDT design allows the switch to control a single circuit with two potential output paths, making it ideal for selecting between two different modes of operation or diverting current flow.

Electrically, the component is rated for a maximum current of 5 Amperes at 120 Volts AC. This rating ensures it can handle the control logic currents typically found in welding machine front panels without overheating or contact degradation. The switch offers three distinct positions (3POS), which typically corresponds to an ON-OFF-ON or ON-NONE-ON configuration depending on the specific machine logic it controls. This multi-position capability is essential for functions requiring a neutral state or multiple active settings.

The termination style is defined as "LUG," specifically referring to solder lug terminals. These terminals feature a small hole through which wire strands are passed before being soldered, providing a vibration-resistant and permanent electrical connection. This is particularly important in the high-vibration environment of industrial workshops where mechanical connectors might loosen over time. As a genuine ESAB replacement part, this switch guarantees dimensional compatibility with the mounting cutouts and internal clearance of the original equipment.
