The problem here started when the switch on our church's organ started going out. It would press, but then wouldn't stay activated when released. I took a look at the organ and found that to get inside I'd have to take the whole thing apart and likely cause who knows how much damage trying to get to the switch, so I took an outside approach as a solution instead. I worked up a design, shown here, for a cam-lock mechanical switch holder that could be placed over the existing electrical switch, keeping it pressed without any troublesome weights or duct tape, and such.
