Switchcraft jack socket
Switching version (three solder lugs) for input jacks and speaker jacks
This is the jack socket that’s commonly used on Fender amplifiers; it has an all-metal construction and an open style. It’s been around – unchanged – for many years. This is a switching version, so it’s suitable for inputs and outputs (ignore the centre lug if you don’t need the switching function). Typically, the switching is used for grounding the tip connection when there’s no cable plugged into an amplifier’s input socket.
Dimensions & info
This socket is mono, with three solder lugs. The shield connections is NOT isolated from the chassis, so your circuit will be grounded to the chassis at this point. It fits into an 9.5mm diameter hole. This is a genuine Switchcraft part.
