    These are momentary switches?

    '

    that push switch is a always noise click click click..

    not good…

    better rather use a quiet silent push switch

    Hi Julian, I'm about to buy the illuminated ones, I need them for a USB powered board, they appear to be 12v/50mA, but what you are showing in here surprises me, how can a 12v led work on a 3v battery?

    why do you use that crappy multimeter?

    Only missing Brown and Violet for the resistor code ….

    Julian, that rating is for the switches them-selfs, not the LEDs. That is a normal rating for this type of switch.

    Now you need a project with loads of switches. They look good btw, I especially like the one with the light in it.

  11. Avataaar/Circle Created with python_avatars Gooberslot says:

    That looked like 12V 50 Mega amps to me.

  12. Avataaar/Circle Created with python_avatars shlomsi2000 says:

    C'mmon Julian, surly you know that the 50mA/12v ratings are for the switches contacts not for the LED.

    Julian did you have an (well almost) empty thrashcan ? ๐Ÿ™‚ (if you know what I mean. Your thrashcan is a incoming-postbox while I use the exact same mesh thrashcan for its intended purposes ๐Ÿ™‚

    I've been using these buttons with color caps for about 8 months now. Quite nice actually. They will bounce about 1/3 of the time, but I've only ever been able to capture a 1 bounce never seen 2 or more bounces. Bounce time lasts about 300 uSec. They snap into standard PCB project boards perfectly. Quite nice. I've ordered more for my projects.

    The 12V 50mA is the switch rating for DC.
