LED illuminated pushbutton switches can display two different messages
May 30, 2012 // Julien Happich
Each of Knitter-switch's LP10 “double legend” pushbutton switch contains a combination of two coloured LEDs – red/blue, red/green and several single colours and one of two messages is visible depending on which LED is illuminated.
As an example, an “ON” message can be displayed if the green LED is powered, while an “OFF” message is shown if the red LED is powered. The LP10 pushbutton switches are through-hole mounted, SPST (Off-Mom) switches with a minimum lifetime of 500,000 cycles. Actuation force is 160gf ±20gf and actuation travel is just 0.25mm +0.2/-0.1mm. Measuring 10x10mm with a height off the PCB of just 11mm, LP10 pushbutton switches features silver plated contacts and terminals rated at 24VDC / 50mA and a maximum contact resistance of 100mOhm. Operating temperature range is -25ºC to +70ºC.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
