Korry® 389 LED-Illuminated 5/8-Inch Switch
A virtual industry standard for versatile, reliable switching
solutions with outstanding illumination
Korry 389 high-performance 5/8-inch LED switches
with magnetic-coil latching for remote release
Esterline offers its Korry 389 5/8-inch LED switches with
the capability to remotely release the switch position
when power is removed from the switch. The magneticlatching 389 version features an electromagnetic coil
that remotely changes the switch contact position
through an external circuit. Applications include engine
ignition, electronic interlocks, and safety mechanisms to
turn off a system when power is lost.
The mag-latch 389 switch delivers uncompromising
performance in system interface capabilities and
lighting characteristics. The unit is designed for
demanding environments and can be found on most
commercial and military platforms.
• Surface-mounted electronics with the latest generation of high-brightness LEDs
• Life-of-the-aircraft component with MTBF 150,000
illumination hours and 100,000 mechanical life cycles
• Reverse-voltage, lightning-strike, and
voltage-surge protection
• Bipolar electrical interface
• Uncompromising performance in system
interface capabilities
• Low coil current: 110 mA maximum at 32 VDC
• Exceptional illumination characteristics such
as brightness output and dimming control
• Optional night-vision illumination
• Subminiature switching for low-level logic-current
and high-current applications

Reliability
The Korry 389 switch has an MTBF of 1.5 million hours,
which varies by configuration and application. The
1.5-million-hour MTBF is for a standard full display,
assuming a 20-degree C ambient operating temperature
and 3,000 flying hours per year. This prediction was
performed using 217 Plus from RiAC™ software.

Electrical Interface Accessories
• M39029 crimp pins: solder-less wire connections
that can easily be removed and reinstalled into the
connector module.
Miscellaneous Accessories
• Spacers: available for insertion between the mounting panel and housing flange to position the cap assembly level with an adjacent lightplate.
• Connector module: a standard electrical interface
that accommodates the M39029 crimp-pin feature.
• Mounting sleeves: two different mounting-sleeve
configurations compatible with either the connector module or PC-header electrical interface.
• PCB header: for installation onto a PCB or CCA.
• Single sleeve: used with the connector module
interface to secure the switch around the mounting panel. This sleeve does not allow for the switch to be
replaced from the front of the panel. Access to the
rear of the mounting panel is required.
• Double sleeve: used with the connector module
interface. This sleeve allows for the switch to be
replaced from the front of the panel.
• Flip-guard assembly: multiple styles available to prevent inadvertent switch actuation.
• Connector-module extraction tool: M22885/108T8234.
Custom Options
For specific applications, custom circuits and lighting
are available upon request.
