The 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 includes a light pipe rather than providing its own illumination. This means that users can fit any LED of their choice to the PCB and implement the switch on top. This means the switches can 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 are also available for these switches, including solid caps and relegendable types with laser-etched and custom-designed sets available. Electrical specifications for these switches include operating temperature range from –40 to +90 degrees C; minimum reed life of 50 million cycles; and maximum ratings of 200V(DC) switching voltage and 500mA current.
