Defense control panels
Avionics switching assemblies
Radar and sensor modules
Industrial high-reliability switching
Product Overview
The KL-A1A from Leach is a 4PDT magnetic latching relay qualified to MIL-PRF-83536 standards. Because magnetic latching relays maintain position without continuous coil power, they help reduce energy consumption in aerospace systems. The 12 amp contact rating supports reliable switching of power and signal circuits in regulated assemblies.
Moreover, the rugged construction is designed for vibration resistance and extended service life. This makes the relay suitable for aircraft platforms, military vehicles, and defense electronic systems. In addition, compliance with military performance standards ensures predictable operation in mission-critical applications.
As a result, engineers rely on KL-A1A relays when building or maintaining compliant aerospace switching systems. Cyndtek supplies new Leach military-grade components ready for immediate deployment.
