I paid a little more for this and for once, I'm glad I did. It's made of quality materials, thicker box and the switch itself uses higher guage metals than the Chinese knockoffs. Wiring and adjustment instructions are on the outside of the case and large enough that they can be read without a magnifier. It of course worked perfectly when installed.

This purchase replaced the exact same switch initially installed 30 years ago. Has worked perfectly since installation. Great testimony to this brand.
