Switchcraft 4330108978 EH35MMSSCB Stereo Jack

The Switchcraft EH35MMSSCB is a professional-grade 3.5mm stereo jack designed for permanent panel-mount installations in studios, broadcast facilities, and custom equipment racks. Built around a D-mount form factor, it fits standard D-series cutouts, making it straightforward to integrate into existing patch panels or wall plates. The solder contacts ensure a secure, low-resistance connection that maintains signal integrity over time — a meaningful advantage over friction-fit or crimp-style connectors in fixed installations.

This jack is a focused, single-purpose component: it provides a reliable 3.5mm stereo connection point where you need one. The black housing gives it a clean look on any panel, and Switchcraft's reputation for durable, professional-grade connectors means it is built to withstand years of use. It is ideal for anyone building or upgrading a studio patch bay, custom control surface, or any installation that requires a permanent, high-quality 3.5mm input or output.
