Miller 120376 SPDT Rocker Switch Details

The Miller 120376 is a high-quality replacement rocker switch found in various Miller welding power sources and industrial equipment. Designed for durability and precise control, this switch is an essential component for restoring functionality to machines with broken or intermittent controls. It is engineered to handle the specific electrical loads of Miller equipment, ensuring safe and consistent operation.

Technically, this is an SPDT (Single Pole Double Throw) switch. This circuit design is versatile, allowing the user to switch a common input between two distinct outputs. The On-None-On action indicates that the switch toggles between two active states, making it ideal for A/B selection tasks, such as switching between process modes or control settings. It does not have a center neutral position.

Specifications:

• Current Rating: 4 Amps
• Voltage Rating: 250 VAC
• Connection: Spade Terminals

The inclusion of spade terminals (also known as blade connectors) significantly simplifies the replacement process. There is no need for complex wiring or soldering; simply slide the existing female connectors onto the switch's tabs. This feature is particularly beneficial for field repairs where time and tools may be limited. When replacing electrical components, always verify the part number in your machine's service manual to ensure compatibility.

At Welders Supply, we stock authentic Miller parts to help you minimize downtime. This switch is a direct replacement for the original factory part, ensuring that your machine's panel retains its original look and feel while restoring full electrical functionality.
