To be continued-
I finally got to my original Prop “STIV Klingon Hand Disruptor” and opened it up to check the fire button you asked about and I can’t see anything without breaking it out which I rather not do- When I can get my son over here he will get a pic up so you can see what I mean.
Thanks. I don’t think there is any markings on the switch anyway. At least the one I saw didn’t have anything to read.
