Voltages and current are only DC voltage 12 v and less than 200ma. What I need is a simple toggle switch.instead of user toggling the switch up and down I want the user to insert or remove a plug in a jack
You could use any one of a number of plug/socket combinations. Simply shorting the connections in the plug would allow you to switch something on by plugging it in.
i want to insert any plug ( no wires connected on this plug) .the metal part of the plug when inserted should short the 2 pin jack. i hope this clarifies
What Steve means is that you can use any plug, short-circuit the contacts internally (solder a length of wire between the contacts) and use it as a jumper. The user doesn't have to see the wire or to know about it at all. A typical 2.5mm mono plug (or 3.5mm for a bit more robustness) could be used for example.
