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.
