A multiple is a required utility sitting efficiently next to modules whose signals should be dispatched to more than a single destination. This a passive module that doesn't require a supply connection. Surprisingly, a multiple could also be used with Klavis logic modules (Logica XT and Two Bits) for additional OR logic. Indeed, these modules allow their outputs to be ORed by simply connecting them together. With 4 jacks in a section of the multiple, 3 inputs to to 1 output and 2 inputs to two destinations are both feasible. Beware that such direct ORing feature might not be available with other brands of modules!
