Product changed? Rugged Metal Pushbutton - 22mm 6V RGB Momen

by St_Arnold on Mon Nov 25, 2019 11:52 am

Hello,

I just got the product in subject and tested it.
Earlier posts on this forum (e.g. viewtopic.php?f=8&t=147227&p=728040&hilit=RGB+pushbutton#p728040 ) lead me to believe that there is a single built-in resistor in series with the common anode and external resistors are required to have mixed colors (multiple LEDs turned on simultaneously).
However, it looks like this has now changed. When I connect +5V to the common anode and GND to multiple cathodes, I get mixed colors without external resistors. Probably there are now three built-in resistors in series with the cathodes instead.
For my project, this is good, but can I be sure that this won't change back in next batch if I order more of these pushbuttons? (We may need many dozens, if not hundreds, in the future.)
Is there a schematic available of the internal LED connections?
