Important:

This switch is presented in three different versions:

  • CAF 12 N: Normal switch with peripheric soldering lugs of conventional types
  • CAF 12 CI: Switch for printed circuits
  • CAF 12 SP: The same presentation as CAF 12 N but the peripheric soldering are replaced by pin type outputs. This arrangement does not permit the addition of extra wafers. As the hole inputs are provided on the same periphery as the outputs, one position is lost with each additional pole. If it is desired to retain these positions the assembly can by provided with all the output pins, but the inputs will be replaced in this case with soldering lugs. The switch CAF 12 N may be supplied with 24 positions at 15°. In this case only the ratchet is different. The 24 positions are obtained by superposing the two wafers and connecting alternatively in zigzags. Only with shorting contacts.

The stop pins are not adjustable
