116830 - Miller Replacement On-Off Rocker Switch for Millermatic 155 & M-15

Restore Your Welder with the Miller 116830 Switch

Is your Millermatic 155 refusing to power on, or is the switch on your M-15 MIG gun acting inconsistently? A faulty switch can bring your welding projects to a grinding halt. The Miller 116830 Rocker Switch is the direct replacement part you need to get your gear back up and running. Designed to fit perfectly into your existing equipment, this switch eliminates the guesswork of trying to match generic parts from the hardware store that might not handle the voltage or fit the panel cutout correctly.

This switch is a Double Pole Single Throw (DPST) unit, meaning it controls two circuits with a single button press—a common safety feature in power equipment. It is rated for 10 Amps at 250 Volts AC, giving it the capacity to handle the power flow of your welder safely. The action is a crisp, positive On-Off click, so you know exactly when your machine is engaged. The black rocker face maintains the original look of your welder, keeping it looking professional and well-maintained.

Installation is generally straightforward for those comfortable with basic tool repairs. The switch is designed to snap into the factory mounting slot on the Millermatic 155 or the M-15 gun handle. Because it is an OEM Miller part, the terminal connections on the back are positioned correctly to mate with your machine's wiring harness. There is no need for cutting, splicing, or modifying the chassis to make it fit. Simply disconnect the power, remove the old broken switch, transfer the wires to the new unit, and snap it into place.

Don't let a small plastic part stop you from laying beads. Switches are mechanical items that wear out over time due to dust, dirt, and repeated use. Keeping a spare Miller 116830 in your shop drawer is a smart move for any owner of a Millermatic 155. It ensures that if your switch fails in the middle of a job, you have the exact part needed to fix it immediately. Trust in genuine Miller components to keep your welder safe, functional, and ready for the next project.
