Siemens-Allis 18-723-775-001 Rotary Drum Switch 8 Pole Adjustable Contacts Used

Siemens-Allis 18-723-775-001 Rotary Drum Switch

8 Pole (can be separated into four 2-pole segments or reduced by 2 poles at a time by removing the bolts and removing the segment(s))

Contacts can be adjusted to engage at different moments from each other by removing the shaft and adjusting the individual discs to one of many stops (set in place by a fine tooth gear inside).

This would be useful if run by a low-RPM motor so that each contact engages in succession and various functions of your mad-scientist project are switched on and off. For example, a traffic light, a street scene where various lights or other events switch on and off as set by this switch.

Condition: Used
