NKK Switches, a leading designer and manufacturer of
innovative electromechanical switches, provides S Series toggle switches for 15
to 25 A 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 12-mm 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 94 V-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 2.0 VAC
for one minute. Most models are UL Recognized and CSA Certified.
S300 and S400 Series switches come standard with 17.5-mm
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 15 to 25 A for resistive
loads at 125 VAC, and 15 to 25 A at 30 V DC. Inductive loads vary based on
model specified from 8 to 10 A at 125 VAC.
