Scottsdale, Ariz. - NKK Switches has added the JB series low-profile, washable tactile switches to its line. A mere 10 mm2, these momentary tactile switches are available in a number of actuator styles including flat buttons and extended actuators. Standard or high-actuation-force models can be specified.
Constructed using a dome contact mechanism, the units give the operator crisp tactile feedback and positive indication of circuit transfer, according to NKK. Also, the single-pole, single-throw switches are sealed to withstand process automation. The rubber-seal construction prevents contact contamination and allows for automated soldering and washing, while molded-in terminals ensure integrity and lock out harmful contaminants. The terminals' slanted design provides a spring-type action to enable secure printed-circuit board mounting and prevent accidental dislodging during automated wave soldering. Terminal spacing conforms to standard 0.1-inch pcb grid mounting.
Design engineers can choose from varying actuator heights and an array of cap styles and colors. Snap-on cap styles include sculptured, flat and framed styles. Engineers can choose legending on any snap-on cap style.
The JB series switches can be mounted in several ways. In a keyboard matrix they can achieve a common bus electrical configuration, using strapped terminals, on a single-sided pc board. Custom keyboards can be designed with a flat-button option or with snap-on caps through a panel cutout. The switches can also be arranged on a single-sided pc-board matrix with strapped terminals to achieve an X-Y electrical interconnection.
JB tactiles are available in both straight and right-angle pcb-mount styles. Typical units such as the JB15FP are priced at 76 cents each in quantities of 1,000. Availability is stock to six weeks.
