274191 - Miller 20A DPST Rocker Switch Replacement

Get Back to Welding with the Miller 274191 Replacement Switch

A broken power switch can bring your entire fabrication project to a halt. The Miller 274191 Rocker Switch is the direct replacement part you need to restore functionality to your Miller welder. Whether your original switch has physically broken, stopped latching, or failed electrically due to wear and tear, this genuine Miller part is the exact match for the original specification. Designed for a straightforward swap, this switch gets you out of repair mode and back under the hood faster.

This switch is a DPST (Double Pole Single Throw) unit, meaning it controls two separate circuits at once with a single button press. This is a standard safety feature in many welders, ensuring that power is completely cut from the internal components when the machine is turned off. With a heavy-duty rating of 20 Amps and 277 Volts AC, it is built to handle the power demands of professional welding gear. The 'On-Off' action is crisp and positive, giving you tactile feedback that the machine is engaged. The black actuator maintains the factory look of your machine's front panel.

Installation is generally simple for those comfortable with basic equipment repair. The switch is designed for panel mounting, meaning it pushes into a pre-cut rectangular hole in the face of the welder and snaps into place. The electrical connections on the back are typically standard spade terminals, allowing you to transfer the wires from your old switch to the new one without soldering in most cases. Always remember to disconnect your machine from power before attempting any repairs and tag your wires to ensure they go back in the correct spots.

Don't risk your expensive welding power source with cheap, generic switches that might not handle the amperage or fit the panel cutout correctly. The Miller 274191 is built to the precise dimensions and electrical standards required by your equipment. Check your owner's manual or parts list to confirm this part number matches your specific model, and order with confidence knowing you are getting the real deal.
