He did say 'please'...
I'm always a little concerned with cryptic demands for wireless switches. So fun and useful, for many things. But unfortunately in these troubled times, one can never be sure who, or how the information posted on forums will be used. Even if the OP really just wants to make a toy car, somebody else might find the schematics with a Google search, and make a toy car, that goes 'BOOM!'. Could be just a bored kid and a large firecracker, or could be some young adult, who got tired of carrying around a backpack full of dynamite, and was having second thoughts... The forum has no control over who views what we post, nor how the information is used. Wireless switches are fairly common in the market place, and can be had cheaply, a simply modified, and considerably less work and more reliable. Don't know the age of the poster, English, probably not the strongest language, but we can only guess at these things, and I have sort of a wild imagination...
