Safran Electronics & Defense has proven capability of development and manufacturing of illuminated pushbutton switches and control panel products. This development covers a wide array of applications for civil and military platforms. The plant in Costa Mesa, California manufactures pushbutton switches, illuminated panels, pilot controls and cockpit control panels. Additionally, Safran Electronics & Defense products have proven superior performance and reliability in the field.
MRO, Flight Controls, Flight Operations Quality Assurance, Auto Pilot Systems, Aircraft Condition Monitoring, Integrated Cockpit Display Systems, and of course, Avionics Illuminated Pushbutton Switches.
The Series 584 PBA LED Lighted Avionics Pushbutton Switch, designed for the life of the aircraft service. It features five aviation and five NVIS (Night Vision Imaging System) compatible colours. The Series 584 PBA is available in momentary action, alternate action, alternate action holding coil and indicator only configurations. Three termination systems are available: Plug-in, Solder turret and IWTS (Integrated Wire Termination System).
The Series 584 LED switch uses the proven four-pole switch contact pushbutton mechanism owing to being qualified to MIL-PRF-22885/110. The switch display is illuminated by surface mount Light Emitting Diodes (LEDs) located within the lamp capsule. Equally, the LED version provides high reliability product in a lightweight, sunlight readable package with options of night vision compatibility, spray-tight sealing, and plug-in mounting.
Safran Electronics & Defense use of its proprietary bi-stable switch contact system, making it important to realise this is what differentiates the Series 584 switch from all other four pole pushbutton switches. This is, due to, the bi-stable design ensuring contact reliability and speed by enabling four switch contacts to be equally stable in both C-NC and C-NO states, unlike sub-miniature switches which require a balanced spring system to maintain them in an activated mode. The switch actuation mechanism is a unique over-center snap actuator which precludes contact tease and inadvertent switch transfer by operators. The Series 584 PBAs deliver fast and simultaneous switch contact transfer based on the bi-stable and switch actuation mechanism. Standard Series 584 LED pushbutton switch delivers 200,000 cycles. While the «Millennium» version delivers more than 1,000,000 cycles.
The Series 584 LED PBA functions with 28-Volt aircraft DC power supply systems. Additionally, the LED PBA Lighting is available linear or step function. The linear dimming is proportional to the external current or voltage input while the step dimming is defined by the desired daytime and night mode voltage levels. Finally, Series 584 PBA illumination life exceeds 100,0000 continuous hours due to optimized Electro-Opto-Mechanical design.
