I am going to take the switch off and see if I can clean or adjust it. It has been sticking almost every day now. I can fiddle with it and unsticks and works for a while, but eventually sticks again. At least the Scrambler switch is only 12 bucks if I have to replace it.

I finally got around to fixing this. The Scrambler switch comes on about a foot of wiring, and swaps out in about 5 minutes. Unplug it from the main harness under the ride side cover, unhook the return spring at the pedal, and slide it out. There is one plastic pin holding it in the middle, which is hard to reach but easy to wiggle out. Removing the exhaust would make access way easier, but it's definitely not necessary.

$12 for the switch, $1.50 or so for the spring.

A bunch of water drained out of it as the old switch came off, so maybe that contributed to the failure. My bike will be three years old in August and it lived outside until a year ago.

For readers who have just come to this: Remember that the Scrambler uses a mechanical switch for the rear brake, and the Bonneville (Thruxton? America? Speedmaster?) uses a hydraulic switch in the brake line.
