| New KB pushbuttons simplify demanding designs  NKK Switches offers the KB series of miniature, illuminated and non-illuminated pushbutton devices designed for a wide range of industrial applications and consumer electronics. The KB series feature many 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. These KB pushbutton switches feature a snap-action contact mechanism ensuring long life and high contact reliability. All models feature UL94V-0 case material.Design engineers can specify three cap shapes, round, rectangular or square. Panel cutout remains round for easier installation regardless of cap shape. Circuit options available include single and double pole in momentary or alternate configurations. Alternate circuits feature a latch down position, instantly indicating circuit status. The KB series has 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 designed to prevent rotation and correctly orients the switch in the panel. Bushing mount models facilitate rear panel mounting. Designers can specify LED, neon or incandescent illumination options, in which each device can be easily re-lamped from the front panel if needed. LED options include a choice of bright or super bright LED's in red, amber, green, blue or white. Matching indicators can also be specified and spot illuminated styles are available. Differing cap styles and cap constructions are designed to enhance the illumination of choice. In order to allow for the legending that many applications demand, caps are constructed to accommodate varying methods of applying legends. write your comments about the article :: © 2007 Construction News :: home page |
