The LED provides visual feedback when the switch is pressed, making them ideal for custom sequencers, control panels, and interactive projects.\n\nEach switch is a momentary SPDT type with four legs for mechanical stability. Two of the four pins act as the common, connecting to one or the other of the remaining pins when pressed. Use a multimeter in continuity mode to verify pin assignments for your design.\n\nKey Features\n\n\nMomentary SPDT Switch – Single pole, double throw with tactile click\n\nBuilt-In Red LED – 3 mm, 20 mA max, 2.1V forward voltage (no built-in resistor)\n\nHinged Step Design – Classic sequencer-style button action\n\n4-Pin Mounting – Mechanically stable; designed for hand-wiring or custom PCB layout\n\nPWM Dimmable – Drive the LED from a microcontroller pin for variable brightness\n\n\n\nNote: These switches are not breadboard or perfboard compatible. They must be hand-wired or designed into a custom PCB. The LED has no built-in resistor — use a 1 kΩ resistor (or similar) to prevent burnout. See the Adafruit LED guide for help choosing a resistor value.\n\n\nIdeal For\n\nCustom step sequencers and MIDI controllers\nControl panels and A/V equipment\nInteractive projects with visual feedback\n\n\nPackage Contents\n\n3× Step Switch with Red LED (Blue Plastic)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2045,"title":"Default Title","sku":"AF-5517","price":9.15,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
