For 5 bucks you have a good stout switch.
How do you think I would feel if you used one I made and it failed for any reason?
You could acquire the parts and have your local hobby shop do it probably for the price of giving them a set of parts.
Sorry.
You can see this is not my original design but another person's and he felt confident enough to publish it in 2002.
Mine work great without any additional electronics attached and it is "just a simple switch". I found the pin flags at Fromeco $2.00 each.
Thanks for reading this.
