This is a DCC Concepts Cobalt Alpha Switch Add-On Pack - Blue (12 Pack)

Alpha-Switch-A and Alpha-Switch-D use the same switch type.

We have created these add-on switch packs so that you can add a second switch where needed, for example when using one on each straight leg of a crossover and another in the middle.

Each pack contains 12 switches, 12 harness and 12 mounting bezels, plus fixing screws.
