22mm S/S RGB LED Light Ring Momentary Pushbutton Switch 6V
This is a stainless steel 3 color RGB LED Light Ring 22mm momentary (On) pushbutton 6V switch.
Features:
- IP65 Rating for dust and water
- Switch rating: 3A/250VAC
- Shape: Flat head (flush)
- Color: Red/Green/Blue
- Voltage: 6v to 48v
- Function: Momentary(1NO1NC)
- Terminal: 8 pin terminal
- (4 pins for LED, one is common anode pin, others are 3 cathode pins for Red, Green, Blue color)
Mounting: Simply drill a 22mm hole into any material up to 1/4" thick and you can fit these in place – there's even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a plastic RGB LED ring.On the back there are 4 metal contacts for the RGB LED ring (one anode and 3 cathodes for each red, green, and blue) and 4 spade contacts for the switches.
LED Function: To use the RGB LED: Power the anode at 3-6V and light up the red, green, and blue LEDs by pulling their designated contacts to ground as you desire – there's a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 1K ohm resistor in series with the LED cathodes to keep the LED current at around 20mA. You can PWM the RGB pins to make any color you like.
To use the switches: There are two electrically separate SPST switches inside the button. The two inner set of spade contacts are a normally-closed switch. When you press the button, these contacts will open. The outer two spade contacts are a normally-open switch. When you press the button, these contacts will open until it is released.
The switch and LED are electrically separated, so to change the color, you can use a microcontroller to both read the contact pins and toggle the color control pins.
