Thought ptm was common terminology for push to make in electronics circles?quote]
Well, I was pretty sure I knew what you meant when you said PTM. But I just call them push-buttons. Or, in your exact case, if you wanted to specify, I would say a momentary NO push-button switch. momentary means that it doesn't latch. It doesn't stay down after you stop pushing it. And NO means normaly open. Meaning that the circuit is open and not passing through the switch when it's not being pushed down. NC, normaly closed, is the other way around. Push it to break the circuit. You may have already known all of this, but..... whatever. :lol: Just tryin' to help.
