Is the contact resistance of a switch important? In BLM?
I’m looking at the ALPS SKPG series: http://www.alps.com/products/WebObjects/catalog.woa/E/HTML/Tact/SurfaceMount/SKPG/SKPG_list.html
(Nice tactile push feeling, but low noise)
It’s 1kOhm vs. 50-100mOhm for the other switches I’ve looked at.
Thanks 
Since I wasn’t sure I tried to switch button functions of my BLM with different resistor values.
It works with 1k, 2.2k, 4.7k - it doesn’t work with 10k anymore (I guess because the current through the diode isn’t high enough)
So, it should be ok for these buttons.
Best Regards, Thorsten.
TK, thanks heaps!
