The other day I posted a question about how to make a simple npn switch, that would take a 12+ and make the switch to ground who's current would be no above 10mA.
I have found that my needs are not of a single switch but a "pulse" of ON/OFF and back ON. Making the ground circuit, then breaking it, and then making the ground again. Hope this makes sense. Very new to electronics here, but I like to learn and do learn fast.
My initial though would be the use of and NPN to a PNP than back to a NPN using maybe a small capacitor in each to slow the signal just a hair so all isn't switched in a micro second. Shouldn't need a lot of time between switches but very small pause the total of which may not exceed a second in time. But that is just me trying to make and uneducated guess here; but trying to learn.
Thanks to anyone who can give me a hand.
