Adafruit Step Switch with LED - Three Pack of Black with Red LED - PB86

These hinged momentary step switches echo the iconic 16-step sequencer keys found on classic TR-808 synthesizers. Not just for musical devices, they also find applications in A/V equipment thanks to their tactile feel and satisfying click.Featuring a built-in red LED, these switches provide clear visual feedback to indicate on/off status or respond to button presses. The robust four-leg design ensures mechanical stability, making them a reliable choice for any project.The switches operate as momentary SPDT types, with two of the four pins serving as the common connections. Understanding their layout is crucial, so refer to the included diagram or use a multimeter for clarity.While they aren't compatible with breadboards or perf-boards, they can be hand-wired or integrated into a PCB for seamless operation. The embedded 3mm red LED operates at a 2.1V forward voltage and supports up to 20mA but requires an external resistor for protection, such as a 1K ohm resistor. PWM dimming is possible via a microcontroller pin, adding dynamic lighting options to your designs.
