I have a set of Jaybrake Classic controls. The master cylinder has the built-in brake light switch. After only a few uses, the switch quit working and, tracing the wiring, the switch shows a short. As I can't detect any user servicable parts, the switch is effectively fried.

I have called the number on the website and left a message but have not recieved a call back.
Does Jaybrake offer a replacement switch and, if they do, how do I get one, how much is it and is it a simple and straightforward replacement?
Does the master cylinder switch need a relay? I use the two-button switch plate for the horn and kill and use relays for both (they work fine and I have never had a problem with them).
