Hi-rel switches designed around broadcast applications

September 03, 2014 // By Graham Prophet
Luso Electronics’ high-reliability switches and keycaps are aimed primarily for use in the broadcasting sector - as well as in many other applications. The products are manufactured by Veetronix (Lexington, Nebraska) a maker of highly reliable keyboard and panel-mount switches for various markets including video and audio mixing-desk equipment, and military and government applications.

The 09 series is based on Veetronix's magnetically-activated technology and offers the features of the company’s existing 07 and 08 series industry-standard switches. These highly reliable devices feature a unique hermetically sealed design ensuring that no moving parts touch the contacts, preventing air, dust, moisture or gases from contaminating the switch and therefore ensuring reliability.

While offering the same exact dimensions of the 08 switch series, the 09 series incorporates a light pipe rather than providing its own illumination. This means that designers can fit any LED of their choice to the PCB and implement the switch on top. These new switches can therefore deliver an overall solution that is simpler to implement as well as being more cost effective as the 09 series is available at lower cost compared to the 08 series.

A variety of keycaps sizes and colours is also available for these switches, including solid caps and re-legendable types with laser-etched and custom-designed sets available. Electrical specifications for these switches include operating temperature range from –40 to +90C; minimum reed life of 50 million cycles; and maximum ratings of 200 V(DC) switching voltage and 500 mA current.
