(LS) Pack 4 Sig-wits (semaphore drivers)

Sig-wit allows for easily controlled operation of semaphore signals by the “wire-in-tube” method.

Both the danger and clear positions of a semaphore arm can be accurately set while a slipping clutch mechanism permits excess travel of the control wire.

These units are designed to operate four single semaphore arms. Typically used in conjunction with Crank-wits.
Full fitting instructions included.
