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 is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
