The 84-8511.2340 is a red illuminated switching element designed for human-machine interface applications. It features a short-travel snap-action switching system with two independent contact points and tactile operation, providing reliable switching even of very light loads. The device is rated for 42 V AC/DC at 0.1 A switching voltage and current, with an operating voltage of 12 V DC ±10% and 10 mA operation current. The contact material is gold-plated silver with a flat ribbon cable terminal, and it achieves a mechanical lifetime of =1 million cycles of operation with an operating force of 4.5 N ±1 N. The device operates across a temperature range of -25 °C to +70 °C and offers IP40 protection on the rear side (upgradeable to IP67), making it suitable for industrial control panels, instrumentation, and applications requiring durable, tactile feedback switching with visual indication.
