The SZW26/LW2620 is a panelmounted, twopole cam switch with a threeposition ONOFFON transfer function. Designed for reliable industrial control, it provides Ith 20A and Ui 660V, making it suitable for medium duty switching in electrical panels. With a 64x64 mm panel footprint and eight fixing screws, it offers secure mounting and stable operation in control enclosures. This is a changeover (transfer) type switch, enabling one common input to be redirected to one of two outputs depending on the switch position.
