Schmersal WKTC521 cross button 30.5mm 101019447

Product Description in English:

The WKTC521 is a four-way switch with a return-to-zero position and four switching positions (left, right, up, down). Designed for demanding industrial applications, including outdoor environments, the switch features IP65 IP65 protection, an anodized aluminum front ring, and a black rubber sealing bellow. The switch provides secure operation with electrically isolated contact bridges and a locking mechanism. Its creeping contact operation ensures precise switching, with a mechanical lifespan of at least 1,000,000 operations.
