    This is my first post so please be gentle:)
    I am trying to switch 3 pairs of wires separately. eg, A toB, A to C and B to C.
    Could somebody please explain to me the simplest switching arrangement using mechanical switches?
    When one pair closes the other two pairs must be open.
    Thank you.

    Please clarify. Are you talking about a lamp that can be switched from 3 locations?


    If so,
    Use two 3-way switches and one 4-way switch.

    GopherT.
    I want to switch three wires in pairs so I can measure the resistance of each pair individually. Each pair will be connected at one end by a switch while I measure the overall resistance of the pair from the unswitched end.
    There will not be any connection to power lines, only to the Ohm-meter.

    Does this switch have three positions?

    Bance, either you have hairy breasts or that is a bad case of plumbers crack.
