Available with or without locking levers, the S Series 17.5mm toggleswitches feature many circuit configurations, including SPST, SPDT, DPSTand DPDT, with a choice of momentary or maintained circuits. Locking leverscan be specified for maintained circuits, providing an excellent choice fordesigns requiring a rugged safeguard to prevent accidental actuation.

Rated at IP67 of IEC60529 Standards, NKK's Series S1 through S29 givedesign engineers the ability to incorporate a reliable toggle switch intodesigns that will be used in a variety of environments where there islikely to be exposure to water and dirt. The standard bat-style actuatormodels also feature an optional splash-proof boot to cover the base of theactuator for additional sealing ability to guard against dangerouscontamination.

All S Series switches feature solder lug terminals and all are panel mountwith 12mm threaded bushings, which are brass with chrome plating. Theseries' mounting design conforms to standard panel cut outs, easing thetask of installation.

Electrical capacities range from 15A to 20A at 125 VAC, 6A to 10A at 250VAC and 15A to 20A at 30 VDC. Both inductive and resistive ratings areincluded in the datasheet specifications. Mechanical life is rated for30,000 to 50,000 operations minimum, depending on model, and electricallife is rated at 25,000 operations minimum.

Standard hardware included with each device is a hex nut, lock washer andan O-ring for panel sealing. In addition, engineers have the option ofspecifying .250" quick connect terminals and ON/OFF inscribed plates.

These devices are ideal for any design requiring human interface via atoggle-style switch in harsh environments, including industrial equipment,heavy machinery, construction equipment, transportation vehicles, aircraft,automotive, outdoor concert and lighting equipment, portable power toolsand telecommunications devices.
