TECHNOLOGY ROUNDUP

Switches and Input Devices

Switches and input devices may appear unglamorous at first sight, but they supply the vital interface that gives the human world access to technology. In this technology roundup, we focus on four product ranges that have featured in recent issues of Arrow Innovation from leading partner suppliers Avago Technologies, Honeywell, C&K Components and NKK Nikkai.



A popular way to input multi-choice data in a small space is the scroll wheel and Avago Technologies offers an ultra slim, five-way scroll wheel device with an inbuilt illumination ring suitable for portable handheld devices such as phones, audio/video and entertainment consoles. In 12 standard configurations, customisable options and flexible connectivity, the AMRX-1510 series allows easy navigation through long menu lists, directional navigation and intuitive selection of functions.



C&K Components supplies a range of low profile, keypad tact switches that combine fast response with positive feel, high performance, ease of use and robustness. Its KMX series offers users a pleasant, tactile feel together with a fast switching response. The devices employ an extremely slim switch design, just 0.58mm thick. Normally open, the switches close with an audible click, a robust mechanism certified for 250,000 cycles. A long travel distance provides a more positive feeling for the user than a standard keyboard.



NKK Nikkai supplies an extensive range of illuminated switches, including incandescent, neon and LED types that enhance function and aesthetic appeal. Rated from 0.4VA (dry contact) up to 20A, all have epoxy sealed terminals preventing flux and moisture from reaching the switch contact mechanism during the assembly process and are available with solder lug, quick connect or PC terminals. The switches, many rated at more than 100,000 actuations, are available in square, round or rectangular shapes and a wide variety of colours and colour combinations via LED colour or filtering in 25 distinct series according to actuation type: pushbutton, toggle, rocker, keypad, slide, programmable LCD switches and displays.



Finally, a closer look at safety in switching with Honeywell and its broad portfolio of interlock, key switch and detection devices that offers solutions for all types of machine safeguarding. Switches and interlocks are key elements for meeting workplace safety standards and keeping machinery operating safely and productively. Product options for critical or potentially critical applications include key operated interlock, cable-pull and hinge-mount switches, all with positive opening contacts or non-contact technologies for door detection and miniature (under 50mm square) to larger, devices.

This brief round up featured some products seen in recent Arrow Innovation issues. The Arrow line card and recent Arrow Innovation issues are a great way to learn more about these ubiquitous and essential devices.
