Power rated rotary switches
NKK Switches announced the availability of the HS16 Series of power rated, standard size rotary switches. The HS16 Series offers engineers the versatility of multiple pole configurations, among other options.
HS16 Series switches are available in single pole through six pole configurations. Multiple poles are achieved by stacking decks, these devices are available in shorting (make before break) or non-shorting (break before make contacts) models.
With a diameter of 65mm, these rotary switches have 30 degree indexing. Engineers can choose to use the HS16 series in two through 11 positions depending on the needs of the application.
Rated up to 12A @ 125V AC or 6A @ 250V AC, the HS16 Series’ mechanical life is 15,000 operations minimum and electrical life is 7,500 operations minimum. The operating temperature range is -10 degrees to +70 degrees Celsius. Terminals are solder lug and made of phosphor bronze material. The HS16 series is cULus Recognized.
Design engineers can specify the HS16 Series rotaries with knurled or D-flat shafts. Shafts are constructed of brass with nickel plating and the cases are molded in phenolic resin material. Two different size knobs constructed of phenolic resin are offered for use with the D-Flat shaft option. These knobs are black with a white indicator line for setting positions.
Standard hardware provided with all devices includes hex mounting nuts, a locking ring and a split lockwasher.
