LED Square Pushbutton

Post by DTM450 »

Hi I was wondering if this LED square pushbutton can support a 3 legged or 3 pin bi colour LED or can it only use 2 legged LEDs

Any and all help would be great thanks

The included lampholder only has 2 terminals, so you would have to improvise the connections. But there is plenty of room in there for an RGB led.

I'll have to check on the measurements. The quick-connects are sold separately: http://www.adafruit.com/products/1152

Do you have any circular led momentary push buttons that you can change the colour of the led similar to the square push buttons aforementioned

Yes we do: http://www.adafruit.com/products/492
The plastic lamp insert will hold up to a 5mm led. But with the insert removed, you could fit a 10mm led in there.

I haven't run tests on these particular switches. But with this type of switch I generally allow a 2ms debounce window.

Well if you run some tests let me know the results
But otherwise these sound perfect for what I need

Putting one on the scope here, I'm seeing between 1400 and 1700uS, of bounce on the close. About 5-600us on the open. So 2ms should take care of it.
