NEW PRODUCTS – Rugged Metal Pushbuttons: RGB Momentary 19mm + 22mm / Rugged Metal On-Off Switches: RGB 19mm + 22mm
By popular demand, we now have rugged metal buttons with a full color RGB LED ring light! These chrome-plated metal buttons are rugged, but certainly not lacking in flair.
We’ve now added these beauties in 19mm momentary pushbutton, 22mm momentary pushbutton, 19mm on/off switch, and 22mm on/off switch. Simply drill a 19mm or 22mm hole into any material up to 0.45″ 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 3 spade contacts for the switch.
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 19mm momentary button: There is one SPDT switch inside the button. Looking at the bottom of the switch, the common contact is the one to the left of the C. Above it are two spade contacts, one labeled NO (normally-open) and one labeled NC (normally-closed). When you press the button, the NO contact will close to the common contact, and the NC contact will open from the common.
To use the 22mm momentary button: 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.
To use the 19mm on/off switch: There is one SPDT switch inside the button. Looking at the bottom of the switch, the common contact is the one to the left of the C. Above it are two spade contacts, one labeled NO (normally-open) and one labeled NC (normally-closed). When you press the button, the NO contact will close to the common contact, and the NC contact will open from the common. When you press the button again, it will revert back.
To use the 22mm on/off switch: 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. When pressed again, the contacts will re-close. The outer two spade contacts are a normally-open switch. When you press the button, these contacts will open until it is pressed again.
The switch and LED are electrically separated, so to change the color, use a microcontroller to both read the contact pins and toggle the color control pins.
