NKK Switches Announces 15A to 25A Panel Mount Toggle Switches

S300 and S400 Series devices feature one through four pole configurations

SCOTTSDALE, Ariz. - NKK Switches, the world's leading designer and manufacturer of innovative electromechanical switches, today announced the availability of S Series toggle switches for 15A to 25A applications. Designed for easy panel mounting, S300 and S400 Series switches also feature many circuit configurations.

Circuit options include single pole through four pole, each available with two and three positions. Maintained and momentary versions can also be specified. In addition, engineers can choose between solder lug, screw lug and quick connect terminals.

These panel mount devices feature robust 12mm threaded bushings. The bushings are brass with chrome plating and conform to standard panel cutouts. Mounting hardware is included with each switch.

The heat resistant resin case meets UL 94V-0 flammability standards and provides high arc and insulation resistance. Mechanical life is rated at 50,000 operations minimum and dielectric strength is a minimum of 2.000V AC for one minute. Most models are UL Recognized and CSA Certified.

S300 and S400 Series switches come standard with 17.5mm long bat-style toggles. Additionally, design engineers can also request devices with flatted levers constructed of black PBT resin. Options include splashproof boots, ON-OFF plates and conical nuts.

Electrical capacities range from 15A to 25A for resistive loads at 125V AC, and 15A to 25A at 30V DC. Inductive loads vary based on model specified from 8A to 10A at 125V AC.

A leading designer and producer of electromechanical switches, NKK Switches offers one of the industry's most extensive selections of illuminated, process sealed, miniature, specialty, surface mount and programmable switches. NKK manufactures more than 3.5 million toggle, rocker, pushbutton, slide, rotary, DIP rotary, keypad and keylock switches, each of which can be used as the foundation of a customized design.
