Semaphore Signal Bounce Servo Unit
A fully programmed PCB designed to reproduce the prototypical signal bounce of semaphore signal arms when returning to danger. It will operate both the upper and lower quadrant signals arms. It can be easily adjusted for both speed and distance of travel using the push buttons and LED indicators built into the PCB. One miniature servo motor is supplied together with linkage wires, ON/OFF switch and a selection of servo arms. Please note that the kit does not include a signal.
