OK
Good product, I only gave it four stars because of the cheesy looking soft plastic. I was expecting it to be smaller, the size was listed in the description, but I don't know metric so my bad. I was making a crystal radio and needed a period look. I was able to cannibalize two switches, shorten the blade, attach a porcelain knob, replace the plastic thumb connections with brass ones and mount them on a ceramic base and It turned out great.

Easy
This was exactly what we needed to turn off a speaker. It sure is easier than twisting and untwisting the wires!

Better than others I have used
Purchased for use in displays where I have to cut the power to a small 12 volt system.works good and engages where it will not come lose very easy.
