196575 - Miller Replacement Power Switch SPST 10A for Millermatic 135/140/175/180

Get Your Millermatic Back to Work with the Miller 196575 Switch

There is nothing more frustrating than flipping the switch on your welder and getting absolutely no response. If your Millermatic 140, 180, or older 135/175 unit is refusing to power up, or if the switch feels loose, spongy, or stuck, it is likely time for a replacement. The Miller 196575 Rocker Switch is the genuine factory replacement part you need to get your machine running again. Don't risk your expensive welder with a cheap, generic switch from the hardware store that might not handle the voltage or fit the hole correctly. This is the exact part Miller put in the machine when it was built.

This switch is a straightforward, heavy-duty On/Off rocker designed to handle the 10-amp draw of your welder at 250 volts. It features a crisp "click" action so you know exactly when your machine is live. One of the best features for the DIY repairer is the connection style. It uses standard 0.250-inch quick-connect tabs on the back. This means you don't need a soldering iron or special tools to install it. Just unplug your welder, open the case, carefully pull the wires off the old switch, and slide them onto this new one. It snaps right into the front panel of your welder for a factory-clean look.

This part is specifically verified to fit a wide range of popular Miller MIG machines. Whether you are running the classic Millermatic 135 or the newer Auto-Set 180, this switch is the heart of your machine's power supply. A failing switch can sometimes cause intermittent power loss, which ruins welds and frustrates operators. Swapping it out is one of the cheapest and easiest repairs you can perform to extend the life of your welder.

Installation Tip: Always ensure your machine is completely unplugged from the wall outlet before opening the case. Take a picture of the wires on the old switch before you remove them so you know exactly where they go on the new one. This simple part can save you a trip to the service center and get you back to laying beads in minutes.
