Pushbutton switches target industrial, CE apps

The KB series of miniature, illuminated and non-illuminated pushbutton switches from NKK Switches target a variety of industrial and CE applications.

Offering a choice of silver or gold contacts, the KB series is rated at either 1A at 125/250V or 1A at 30Vdc for power models. Logic-level devices are rated for 0.4VA maximum at 28Vac/dc maximum. The mechanical life for all versions is 100,000 operations minimum.

Unique features
The KB series pushbutton switches feature many unique characteristics including molded-in terminals to lock out flux, dust and other contaminants; a compact body size of 12mm diameter for standard panel cutouts, and an 8mm panel thickness mounting capability. In addition, the KB series switches feature a snap-action contact mechanism that ensures long life and high-contact reliability. These switches are UL Recognized and CSA Certified. All models feature UL94V-0 case material.

Caps can be specified in three shapes—round, rectangular or square—and can accommodate a number of legending methods. Design engineers can use NKK's Legend Maker, an online tool, or download legend packets from the company Website.

Panel cutouts are round for easier installation regardless of cap shape. Circuit options available include single-pole and double-pole in momentary or alternate configurations. Alternate circuits feature a latch down position, instantly indicating circuit status. Audible and tactile feedback with responsive operation is standard.

Mounting options
The KB series also features solder lug terminals and can be ordered in snap-in or bushing mount models. Barrier style cap frames are also available. Snap-in versions feature a stainless steel frame, which is specially designed to prevent rotation and correctly orients the switch in the panel. Bushing mount models facilitate rear panel mounting.

KB illuminated devices offer a number of options for front panel appearance and design engineering requirements. Designers can specify LED, neon or incandescent illumination options. LED options include a choice of bright or super bright LEDs in red, amber, green, blue or white. Matching indicators can also be specified and spot illuminated styles are available.

Pricing is $4.27 each in quantities of 1,000. Availability is from stock to six weeks.
