Our rotary switches are highly versatile, multi-pole, multi-position and multi-functional. Standard rotary wafer switches are suitable for use in applications up to 300 Volts.

NSF offers a variety of rotary switches which have different index mechanisms and wafers, dependant on the current and positions required.
