Treadlite Switches are known for their long lasting design. Many years ago I used Treadlite switches in a large metro cab system dispatch center. They worked flawlessly in that very busy environment. This one is new, on the base and ready for you to wire to your gear. If you have never used a Treadlite switch, they are super simple to set up. See the last image. Simply remove the switch from the base with two screws, wire up to the switch (either normally open or closed) and away you go. If you do ever wear one out, simply get another single switch and put it on the base. Treadlite switches are heavy, they tend to stay put and not walk around.
