    Hi, basically I just need some quick help with finding out which tabs correspond to what for this input jack. I haven't come across a jack that has the identical structure as this one. Is this a mono, stereo, or grounding jack? I'm thinking it is a grounding jack as it doesn't look like the mono/stereo jacks online.

    Awesome! So if I am wiring an input signal as well as a ground, what would I do with the switch tab? Do I short the switch tab to the sleeve tab (ground)?

    Thanks again!

    It's a mono jack with a normally closed switch that grounds the input and the ground opens when the plug is inserted.

    Finding which tab goes to where is simply a matter of looking at the layers of brown stuff and metal. Bottom tab is ground, top tab is tip.

    Thanks for the reply! I'm still just wondering what to do with the switch tab now. Do I connect it to the sleeve tab?

    If you want the input grounded when no plug is inserted, you wire the switch tab to ground (sleve). If you want something else to be on the input when no plug is inserted, wire it to something else.

    This type is often used for battery operated devices. The battery is connected through the shorted contact and is disconnected when you plug in the male jack. This allows you to run a device from an AC powered adapter or from batteries.

    The fact that it is 1/4 inch mono means it is probably intended for use as a 'patch panel' input. A signal is passed through the shorted connection, but is disconnected when you 'patch' in another signal.
