“Factory” has settings to suit a variety of moods. A leisurely idle speed with only lights and chain running, a light workload day sending an occasional marble down a chute, on up to a frantic workload of a factory catching up with back orders. Moving the control lever to various positions mechanically alters both the number of trip actuators allowed to set as well as the number of times each set actuator is allowed to actually trip a marble. 1.5m h x 1.7w x .23d .
