The BESTECH BS-UKS and BS-UKT are elevator buffer switches designed for lift pit safety. Both models are IP65-rated waterproof safety circuit switches that cut power to the safety string when the lift buffer is compressed.
The BS-UKS features a straight vertical plunger (Senkrecht) for top-mounted installation. The BS-UKT uses an angled side plunger (Tangential) for side-mounted installation. Both serve as lift safety buffer switches and elevator limit safety switches in UAE elevator systems from Otis, Schindler, Kone and Thyssenkrupp.
