Hello to all! Does anybody know what type of this switch is? Seams like there is a couple of "rebranders" using it even on expensive lights like Big Blue. I tried to do some searching but even after hour spent on google I couldn't find any info where to get these. From what I understand this is mechanical sealed button with spring and orings, touching electronic switch underneath. The question is if this system could be replaced or modified...

Thanks for you help!
