Found a little info: WHat to do with dead Sunwayman T40cs
I dont know of a driver that has a 24mm dia. and uses a e-switch.
You might be able to piggy back a nanjg driver with the zener mod with Jonnyc Star momentary. That would probably work if you didn’t destroy the pcb looks like from the pic there’s plenty of room. I Have one running in a SRK piggy backing the original board with Jonnyc Star momentary firmware with a e-switch but I didn’t have to use the zener mod.
If you contact RMM on this forum he might have a better solution for you. You can visit his site at Mountain Electronics
