Spacer decks can be supplied to facilitate PC board layouts of
three or more decks. A spacer deck does not have any
terminals and provides no switching function. Dimensionally, it
requires the same space as one normal switch deck. Spacer
deck can be placed at any location in the switch, per your
instructions. Switches which include spacer decks are procured
under a special part number.
Shown for a two deck switch.
Bushing mount is recommended.
