Keywords:power-rated illuminated switches? industrial applications? pushbutton?

Several families of power-rated illuminated switches for industrial applications have been launched by NKK Switches Inc.

The LB, YB, UB and UB2 pushbutton switch families range from 3A at 125V/250Vac or 30Vdc, to 5A at 125V/250Vac or 30Vdc. The switches come in various shapes including round, square and rectangular with multiple cap styles, illumination types and colors. Bi-color versions are also available. Additional options include built-in resistors to reduce and simplify assembly time. Low profile and compact body styles with solder lug/QC or PC terminals are standard.

Unique characteristics include compact body designs to minimize behind panel depth and molded in epoxy-sealed terminals to prevent the entry of flux, dust and other contaminants. The switches are UL recognized and CSA certified with flammability ratings of UL 94V-0. YB and LB series are also offered sealed to IP65 of the IEC60529 standard (similar to NEMA 4 & 13).

All NKK power-rated illuminated pushbuttons are available in SPDT or DPDT and momentary or maintained circuits, which come standard with a latch-down feature that indicates status. Stainless steel clips provide secure mounting for snap-in models in the LB, YB, UB and UB2 series. Bushing mounts can be specified for the LB and YB switches and accessory options include protective guards and dust covers.

Each of these switches feature specially-constructed caps that accommodate cap legends. Engineers can use NKK's Legend Maker online tool to aid in panel design.

Pricing starts at $4.57 in quantities over 1,000.
