Hi all,
i've been puzzling over this for a wee while and can't figure it out.
I have a mono jack socket with a normally closed tip-switch. The socket is for input voltages. I want to detect whether there is a jack connected using the tip-switch but can't figure out how to do it. Does anyone know of a wee schematic to demonstrate that? I don't want to use an IC to detect the presence of a jack plug in the socket.
Thanks
NM
p.s. i normally have the tip-switch connected to ground so that when a plug isn't in the socket the tip isn't floating
