Can someone help me with a part number?

[japhy]

Hi, all. I'm really new to all of this, and I'm not so brave as to attempt anything but a novice level repair.
I have an SWR Workingman 15 (from 1997) that has a bad input jack. And a horrible hum (but I'm pretty sure--and hopeful-- that they are related).
I just don't know what jack to get. I'm trying to get a mouser part number, but I don't know if this is switched or not. Its plastic and has 3 terminals on the back to solder to.
Thanks in advance for your help.

Hard to match up a switch without seeing a pic of the entire switch & is there any thing written on it
I just googled the amp & it looks like one that marshall uses on there mg series but not sure as in you pick they solderd direct to it

This might work but it has the plastic bushing:

Welcome to the place.

Most of the Workingman's 15 amps have metal threaded input jacks. They are switched, to ground the input when there is no cord plugged into the jack. The entire preamp circuit grounds at that input jack.

The Switchtcraft number is 112AX (Mouser part # 502-112AX)

The insulated plastic version is number N112AX (Mouser part # 502N112AX)

This is from one of the Pre-Fender models. I don't know if that makes a difference.
This is a picture of the front plate (not my pic. Found online):

All of the other input jacks are plastic, too. They may have been switched out at some point, though.
From what I can gather (and I may be WAAAAAY off here), that bare wire running off to the top of the picture may be tied to the ground. It connects to the jack below it. That's probably the switch you are referring to?
If I knew my way around a schematic, that would probably help. A lot.

This is the best picture I have of the broken jack right now.

It's the N112AX that 52Bill mentioned above.

Ordered. Thank you all very much for your help.

The switch is part of the jack and is the third terminal on the back. There are three terminals 1- Tip, 2- Shield and 3- N.C. switch contact (connected to the tip connector).

The switch is typically used to quiet the amp when there is no cord plugged into the amp, or to create a higher gain input level jack. If you look at a lot of schematics you will see the switch contact as an arrow that connects to the tip (hot) contact.
