Great Test Switch
The switch and safety cover are well made. The red cover is very noticeable and easy to see. I actually used the switch as a test switch on an electric hot water boiler that I had installed. I test the boiler at the beginning and the middle of the heating system. The switch allows me to bypass the thermostat control in order to hand operate the boiler. It allows me to take amp readings of each individual heating element to access the complete boiler operation without having to change the thermostat setting. I installed instruction labels in the event another technician does the actual tests.

So far, very good.
Large, well-made switch with a safety cover. My daughter had purchased a very expensive car tire inflator (of course, no receipt, no box etc). Rather than go through the company and purchase their cheap 5 cent switch for $22 shipped, I ordered this. The safety cover is large, very positive and protects the toggle switch while in the car trunk. Very happy with this.

Good switch. Jury is out on the cover
I bought this to control a sprayer on my tractor. The cover is nice to keep you from accidentally hitting the switch. The switch seems like a quality component, but the plastic cover seems weak. Not sure how long it will last (I'm hard on stuff) but it works great now.

Material fit, finish and operation are all quite good.
Arrived on time and as described. These are my second purchase from these fine folks and I'm sure the switched will work perfectly as did the original switch. Material fit,finish and operation are good. Highly recommended.

ignition switch for a race car
I wanted to replace the ignition switch in a race car. Because we have had a couple times the switch did not appear to open. This is a heavy-duty switch.

Works great for 48v electric cart switch
Works great. I got this for the main switch (tow/run) on a 48v electric golf cart restoration project. The cover makes it obvious which switch this is and admittedly adds a fighter pilot feeling when turning the cart on. :-)
