The 112BX 1/4" 3-Conductor Jack with Solder Lugs from Switchcraft is suitable for panel/chassis and PC board mounting and comes with a double open circuit solder lug. Unitized molded housing protects springs, provides mechanical and electrical reliability, minimizes leakage and provides low capacity between springs. It mounts on minimum 0.625” centers in rows or arrays.
