SL3KT (pronounced "Select")  is a simple three-channel switch module for Eurorack Modular Synthesizers.  

Three independent, two-way switches allow for users two select between different sources or destinations of both CV and Audio Signals. Useful for many tasks in a Eurorack system such as sequence selecting, CV selecting, boolean logic operations, group switching, group routing, gating, waveform mixing, and so much more!
