## Customer Reviews

### ⭐⭐⭐⭐⭐ Good price
*by D***N on March 24, 2025*

I recently bought a new side by side Kawasaki Teryx4. I bought it with no accessories do to the ridiculous cost through dealership. I connected the hot side to the hot side of starter solenoid and ran a jump wire from my headlight power supply (which was key on power) to the control post. Then added all my accessories to this continuous duty switch. Light bar, amplifier, heater, winch controls, ect. Works great.

### ⭐⭐⭐⭐⭐ Good Price
*by A***R on April 7, 2025*

Nice Product

### ⭐⭐⭐⭐ 40 to 50 amp’s intermittent & not sealed
*by B***S on May 14, 2025*

Took one relay apart to look at contacts inside. The relay cover is not sealed in any way, cover just slips and clips over relay body. Not suitable for moist or wet environments or heavy dust dirt sand environments. Likely only suitable for about 40 amps continuous and maybe 50-60 amps at about 5 seconds. Anything more and expect something similar to a nuclear meltdown.
