22mm Push Button with RGB Lighting 5V - Stainless Steel

This stainless steel push button is mounted in a 22 mm hole and has an illuminated RGB LED ring. The three colours can be controlled individually by a microcontroller such as Arduino, and mixed via three PWM outputs. The series resistors for 5 V are built in, so the LEDs can be connected without additional resistors.

Recommended Accessories:

• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy

Features:

• Stainless steel housing, protection class IP65
• RGB LED ring with built-in series resistors for 5 V, also usable with 3.3 V
• 4 gold solder terminals for the switch: normally open and normally closed
• 4 silver solder terminals for the LED: one common cathode and one anode each for red, green and blue
• Momentary action: the contact is only closed while the button is pressed
• For 12 V or 24 V, connect a 1 kΩ resistor in series with the LED cathode to keep the LED current at around 20 mA

Application Examples:

• Control button with status indication on enclosures and control cabinets
• Button that changes colour depending on the state, for example green for ready and red for error
• Switching with normally closed and normally open contacts, for example interrupting one signal and switching on another when pressed
• Start and stop buttons for setups with extra-low voltage
