These hinged momentary step switches are reminiscent of the 16-step sequencer keys found on classic TR-808 synthesisers. Each white switch has a satisfying tactile click and a built-in red LED for status indication or visual feedback. Sold in a pack of three.
The switch is a momentary SPDT type with four legs — two common pins and two throw pins. The four-leg design provides mechanical stability. Check the pinout diagram or use a multimeter in continuity mode to identify the pole and throw connections.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
