I have a couple of spares for sale. They are side specific for wire routing, and the switches are fragile, and can literally fall apart in your hand. I may not have the black button, I will have to check for one. If you are going to install one, make sure the wires go where they are supposed to, I got one trapped near one of the hold down bolts, and about 3 months later it worked its way to the bolt, causing a short.
