Description
A button is a button, and a switch is a switch, but these translucent arcade buttons are in a class of their own. Particularly because they have LEDs built right in! That’s right, you’ll be button-mashing amidst a wash of beautiful light with these lil’ guys. They’re the same size as common miniature arcade controls, and require a 24 to 28mm diameter hole for mounting. They are sometimes referred to as 30mm diameter buttons.
The buttons screw in place so you can use them in panels up to ~20mm thick, and will cover up if the hole if it isn’t perfectly round and clean. The action is smooth, without a strong click, yet you can definitely feel when the button is pressed. A tiny micro-switch is pre-installed, with gold plated contacts.
Even unlit, they look fantastic: all of the colours have a crystal translucent glossy look. As noted they have LEDs with resistors built in, buried in the button body. Next to the switch contacts are two additional contacts for powering/controlling the LEDs. The two LEDs are connected in parallel with ~1K resistors each, so you can power the LED from a microcontroller pin or direct from 5V (say USB) with 10mA draw. Recommended for 5V but you can go down to 3.3V but they’ll be dimmer. Only 2mA per button. When you first connect the LED if it doesn’t light up just switch the connectors around.
