Good switch at good value
Weatherproof but made sure installed upside down so water can drain off. Works well.

Keeps the lights on the tractor running
I have been through countless good quality parts store switches with lifetime warranties. The local parts guys have never refused to replace one free of charge, but replacing switches on a regular basis is a hassle and, quite frankly, many times you don't know it's busted until you turn it on and it fails to light. Even though my light switches on the ol' tractor weren't "in the elements" directly, I decided that the failure had to be seepage related and decided to try one of these. I have not has a failure on the original switch, while I have been through two of the old style during the course of my experiment. To me that's proof enough. These switches and boots are not the cheapest, but they are well-made and hold up. Worth the price. Make sure you order the switch with the boot. They DO NOT come as a set!!!!!!!!!!!!!

High quality switch
I got this switch to replace the broken one in the bathroom vent fan of my RV. I wanted something that would stand up to the moisture in that environment and outlast the RV. I think I've found that in this switch. It appears to be well made, and turns on/off with a nice positive click. It's not "cheap," but I reckon you get what you pay for.

Quality switch but significant snap action
I bought several of these switches to rebuild a DC switch panel in my 40 year old sailboat. These are high quality switches, but I'll note they require significantly more operating force than similar toggle switches including the ones I'm replacing. I recently also purchased Blue Sea systems AC and DC circuit breaker panels, and the force required to operate these toggle switches is probably double that required to operate the circuit breakers. The toggle switches do not have the smooth operating action I was hoping for.

Flawless Switch
I used this switch for a remote on and off switch for an amplifier on my boat. Works flawlessly and easy to install. It's in the elements all the time so it being waterproof is definitely a plus.
