The 84-8511.4620 is a switching element designed as an operating and indication part with yellow illumination. It features a short-travel snap-action switching system with one normally open contact, gold-plated silver contacts, and a plug-in terminal (2.8 x 0.8 mm) for reliable electrical connections. The device operates at 24 V DC ±10% with a switching rating of 42 V AC/DC at 0.1 A, maximum power of 2 W, and an operating force of 4.5 N ±1 N with approximately 0.5 mm travel distance. It offers excellent mechanical reliability with a lifetime of =1 million cycles, operates across -25°C to +70°C, and meets IP40 protection standards (upgradeable to IP67). This switching element is ideal for human-machine interface applications requiring tactile feedback, reliable light-load switching, and compact integration in industrial control panels and instrumentation systems.
