Military Aviation Aircarft Switch AN24-H 2Pins

Product Overview

The AN24-H 2Pins Aircraft Switch is a rugged, military-grade rocker switch designed for demanding aviation and defense applications. This military rocker switch features a simple 2-pin, single-pole single-throw (SPST) normally open configuration, providing reliable on/off control for lighting, avionics, auxiliary systems, and ground support equipment. Rated for 28V DC / 10A resistive load and capable of switching low-level signals down to 10μA/10mV, the AN24-H delivers excellent contact stability, low resistance (≤50mΩ), and high insulation resistance (>500MΩ). Its sealed construction (IP67 front panel) protects against moisture, dust, and fuel vapors, while the robust rocker actuator provides positive tactile feedback and long mechanical life (50,000+ cycles). As a core product in YM’s aviation switch portfolio – which includes Aircraft Rocker Switches, Aviation Swing Arm Switch, Micro switch, Aviation Button Switch, and Aviation Encoding Switch with Military Grade – the AN24-H delivers uncompromised performance for cockpit panels, weapon control boxes, and field-deployable systems.

Key Features & Advantages for Military Aviation

• Military-grade durability: Designed to MIL-PRF-8805, the AN24-H withstands high vibration (10g RMS), shock (50g), and temperature extremes (-55°C to +85°C) – ideal for cockpit and external aircraft mounting.
• Positive tactile feedback: Rocker mechanism provides distinct actuation feel and audible click, reducing pilot error in high-stress environments.
• Sealed construction (IP67): Front panel seal prevents ingress of moisture, dust, and fuel vapors – critical for unpressurized bays and ground support equipment.
• Simple 2-pin SPST NO configuration: Easy to wire as a direct on/off control; compatible with 28V DC aircraft power systems and low-level signal circuits.
• Low contact resistance & high insulation: ≤50mΩ initial resistance and >500MΩ insulation ensure reliable switching of avionics signals and power circuits.
• Optional illumination: LED or incandescent lighting for night operations (NVIS compatible versions available).

YM’s engineering advantage: The AN24-H shares proven sealing and contact technology with our military rocker switches and certified aircraft rocker switches families. For complete panel integration, YM also offers Aviation Rocker Switch with military grade, military grade rotary switches, aviation encoding switch with military grade, and gx Aviation Connector – a one-stop solution for aircraft cockpit and avionics controls.

How to Install & Use the AN24-H Aviation Rocker Switch – Step by Step

1. Select the correct configuration: Confirm that SPST normally open (2-pin) meets your circuit requirement (load on when rocker is pressed down). Verify voltage and current ratings match your load.
2. Panel cutout preparation: Standard cutout size: 21mm x 31mm (for single rocker). Use a panel punch or CNC router for precise hole. Deburr edges.
3. Mounting: Insert the switch from the front of the panel. Secure using the snap-in clips (standard) or mounting ears. No additional hardware needed.
4. Wiring: Connect wires to the two 0.250” quick-connect terminals (or solder lugs). Polarity not required for standard SPST. Use MIL-spec wire (18-20 AWG) and insulated terminals.
5. Sealing (optional): If using a silicone boot seal, stretch it over the actuator before panel insertion. Ensure the boot flange seats flush against the panel.
6. Functional test: Apply power and press the rocker (down = ON). Verify continuity across terminals using a multimeter. For illuminated versions, check LED brightness.
7. Maintenance: Periodically inspect for cracked housing or loose terminals. Clean with mild detergent and damp cloth – do not immerse.

Pro tip for avionics engineers: For NVIS (Night Vision Imaging System) compatibility, specify the “N” option with filtered LED (green or red at 590-670 nm). YM can provide custom legend engraving on the rocker cap (e.g., “ON/OFF”, “MASTER”, “FUEL PUMP”).

Application Scenarios & Key Buyer Benefits

Typical Military & Civil Aviation Uses

• Cockpit control panels: Master power, avionics bus control, auxiliary lighting, and fuel pump override.
