NEW PRODUCT – Waterproof Metal On/Off Switch with Green LED Ring [16mm Green On/Off]
NEW PRODUCT – Waterproof Metal On/Off Switch with Green LED Ring [16mm Green On/Off] . These chrome-plated metal buttons are rugged and waterproof and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2″ thick and you can fit these in place, there’s even a rubber gasket to keep any water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a green plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the blue LED ring (+ and -). Connect 3 to 6V to the LED to have it light up nicely, there’s a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 470 ohm resistor in series with the LED connection to keep the LED current at around 20mA.
This button is an on/off switch button, when you press it the ‘normally-open’ contact shorts to the common contact and the button stays ‘pressed’. When you press it a second time, the button springs open, and the contacts open up again.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
