Bought this switch to control the electrical waste water valve in my RV. The original switch was fine but wanted to add another location. While it's a minor point, I like the spring-return action of this switch. The original switch is very hard. I bought the switch holders offered by Revain but the installation would be tight so they have not been used. The switch fits snugly into the dash, but note that there are very few protrusions on either side of the switch. If you don't make the cut carefully, you can peek into the dash on either side of the switch. I would buy this again.
