The Schmersal ESS21S2.V is a robust selector switch designed for industrial control applications. This 30mm, two-position switch features a maintained mechanism, meaning it stays in the selected position until manually changed. It includes a key-operated function with the key removable only in the right position, providing an added layer of security for operator control. The switch is built with a plastic base and a durable metal bezel, and the black operator is made of metal with a round 36mm design. Note that this model requires contact blocks to complete the assembly. Distributed by BSP Automation, the ESS21S2.V offers reliable performance in environments where protection up to IP65 is needed.
