Lots of connectors and jacks have two pins... just have to know where to look for them.

That's an odd question. There are probably many 1000s!!!! Most DC connections are 2 wire and many low voltage AC are two wire. Speakers, microphone, even your everyday table lamp uses 2 wire connections. Inside your computer, many things use 2 wires, including your power and reset switches. Most fans only use 2, though their may be another for speed control/monitoring.

Oh, and female connectors don't have pins. The have sockets that accept pins - that's why they are called female, and not male.

The first thing that came to mind for me was this.

the 2 pin female jack i wanted should have only 1 socket and the plug i want to put in this socket need to close the two pins on the rear end of socket.

if i am not clear in explaining, what i wanted is spst switch but not the conventional up and down. but plug insert type.

i have googled but not found what i want.

thanks.

Well, I am afraid I am still confused. You want the inserted plug (which you don't have yet) to physically move a contact in a socket (which you don't have yet either) until it contacts a 2nd contact - which then connects (shorts out) the two wires in your plug. Is that right? What voltage and current rating? If high enough, you will turn that socket into a very hot light bulb - for a second.

Two wires to be connected on the pins of a socket. The plug which is inserted should short these wires,like a simple switch.if the plug is not inserted the wires remain open. The ratings will be DC 24v max and 500ma max. Thanks

The normal design is to have male pins (header) and use jumpers to short them. So I think you're talking about simple headers and jumpers.

But I guess you probably want the pins insulated through some method (making them a sort of female terminal, and you want a kind a jumper that would fit inside the female header and short it.

Here's a lot of female headers with the metal contacts protected by the external plastic:

Anyway.. it's really not clear.. maybe open up Paint and draw something (or if you have a camera draw something on paper and make a picture) and we can give you some suggestions based on your drawing.
