About Us

“We are what we repeatedly do. Excellence then, is not an act, but a habit.” -Aristotle

We are a family owned and operated California Corporation dedicated to the design, manufacture, and distribution of innovative and industry-leading products.

Perfect Switch, LLC is credited with designing the world’s most efficient solid-state switch. This internationally patented technology is made available through the POWER-GATE product line which includes high-current solid-state relays, battery isolators, breakers, voltage sensitive disconnects, and OR’ing devices.

Mobile Welding & Power is the only manufacturer and supplier of universal, solid-state control units for the alternator actuated welding world. Engineered to provide unparalleled flexibility, we manufacture the MOBI-ARC line of products and accessories turning common automotive alternators into a portable power supply capable of welding, and cross-voltage-platform jumping.

Our prevailing attitude – a willingness to challenge conventional thinking – drives us to succeed. We are both a proactive and reactive organization. We have responded to user’s needs by engineering products that are both simple to use, and simple to install. Our goal is to provide better value through increased performance, reliability and quality. We’ve succeeded.

Our devices can be found on Boats, RV’s, Helicopters, Airplanes, Roller Coasters, Military Apparatus, Test Fixtures, and of course, Cars and Trucks.

With customers like NASA, Lockheed Martin, Bombardier, Bell Canada, L-3 Communications, General Dynamics, Raytheon, Disney, and the US Navy, Army, and Marine Corp, it’s no mystery why our products become the industry standard when it comes to solid-state switching, battery management, alternator actuated welding, and cross-voltage platform jump-starting.
