PRODUCT SHOWCASE MEC high performance tactile switches The MEC Multimec switch series has three standard actuation forces and is only available in high temperature material in order to stand today’s advanced soldering processes. Furthermore, the switch can be supplied with one or two LEDs integrated on it in order to provide excellent illumination. Night vision (NVIS) LEDs are also available. They have >10 million lifetime cycle, NO or NC/NO functions and is sealed to IP67. Custom legends are available. The Multimec is not just an ordinary switch but manufactured to be the best possible switch for the most demanding customers.

Website: www.microchip.com Covid-19 “virus” malware can be deadly for computers As if we didn’t have enough to worry about with coronavirus for humans, so far there have been five malwares identified which have the ability to do serious damage to your PC. As reported by ZDNet.com early in April (no, not April 1!), one of these can not only trash your PC files but also rewrite your computer’s master boot record (MBR). siliconchip.com.au While an expert with the right software should be able to restore the MBR and files, it will take time and could be very costly. ZDNet report that some of the viruses appear to be malware, demanding payment for the “cure” – which may not even exist.
