This enclosed 1/4-inch (6.35mm) double circuit mono jack is housed in a durable molded plastic body to prevent grounding against the chassis panel. Designed to fit a standard 3/8-inch (9.52mm) mounting hole, it provides internal spring switching contacts that operate automatically when a 1/4-inch plug is inserted or removed.

The fully enclosed housing protects internal contacts from dust, debris, and accidental shorting against adjacent components inside tight radio chassis, amplifier cabinets, or control panels. Heavy-duty solder terminals extend from the rear for straightforward wiring.
