I have a "Sierra" 3-way light switch that needs replacing but I can't find where to get that brand. It is unique. It is modular. A metal plate with a snap-in switch on top, a space, and a second snap-in switch on the bottom.

Iv'e tried two different Leviton switches from Home Depot. One works partially the other doesn't work at all.

There is no part number on the switch just the brand name "Sierra." Does anyone out there know where to get a Sierra switch?
