24608P-01 – David Clark Headset Jack and Switch U94A/U

Available now on the Airparts.aero Marketplace.

Overview

The David Clark 24608P-01 is a genuine OEM jack and Push-to-Talk (PTT) switch assembly, commonly identified by its military designation, U-94A/U. This is a rugged, high-reliability interface component designed for use in military, aerospace, and high-noise industrial communication systems. It combines a female receptacle for a standard U-174/U helicopter-style plug with a large, integral PTT button. This allows for the creation of robust extension cords or panel-mount interfaces that provide both audio connectivity and a positive-action transmit switch in a single, durable housing.

Key Features

• Integrated Push-to-Talk (PTT) Switch: Features a large, high-cycle PTT button integrated directly into the jack's body. This provides a durable and tactile switch for keying the radio transmitter, designed for use with gloved hands in demanding environments.
• U-174/U Receptacle: The jack is designed to accept the standard U-174/U single plug found on most military and civil helicopter headsets, as well as ground support and other rugged communication headsets.
• Durable, High-Impact Housing: The body of the assembly is molded from a tough, high-impact polymer, providing excellent durability and resistance to damage from drops, impacts, and crushing forces.
• Strain Relief & Wiring Provisions: Designed with robust provisions for attaching and strain-relieving a multi-conductor cable, ensuring the internal solder connections are protected from stress.
• Genuine David Clark Component: As a genuine David Clark part, it guarantees the use of high-quality switch contacts, precision-molded components, and the reliability expected for mission-critical communication equipment.

The U-94A/U is a 4-conductor jack assembly. The contacts are typically designated for Microphone High (Mic+), Microphone Low (Mic-), Earpiece High (Audio+), and Earpiece Ground (Audio-). The integrated PTT switch is a simple, momentary, single-pole single-throw (SPST) switch. When depressed, it closes a circuit between two dedicated contacts (often using the Mic- and a separate PTT ground). This closed circuit signals the radio or intercom system to enter transmit mode. The robust mechanical design ensures that the PTT function is physically separated from the audio lines to prevent crosstalk or interference, providing a clean and reliable keying mechanism.

Note: This is a component part that requires soldering and proper wiring to a communication cable for use. Installation and wiring should be performed by a qualified avionics technician or electronics specialist in accordance with the wiring diagram for the specific radio or intercom system it will be connected to.
