Several years ago I had purchased several Ti on-off tail switches with trit inserts that I used in my Sunwayman V10R lights and Ti bodies made for the same and other Ti lights. Now I have found that the internal electronics need need to be replaced-not the switches, just the internal electronics. I´ve been out of touch for a while now so I`m not up to par with what is happening in the custom Ti build scene and therefor do not know who to contact to be able to replace the needed parts. Any help/links to such info will be greatly appreciated. Even better is if you have such switch internals for sale!
