S300 and S400 Series Toggle Switches
NKK’s 15- to 25-amp panel mount toggle switches
NKK Switches' S300 and S400 series toggle switches are designed for easy panel mounting and feature circuit configuration options ranging from single pole through four pole. Each is available with two and three positions, and maintained and momentary versions can also be specified.
These devices feature robust 12 mm threaded bushings, and the heat resistant resin case meets UL 94V-0 flammability standards and provides high arc and insulation resistance.
S300 and S400 series switches come standard with 17.5 mm long bat-style toggles. Additionally, design engineers can request devices with flatted levers constructed of black PBT resin. Options include splash proof boots, ON-OFF plates, and conical nuts.
