secondary Magnet in each Switch Unit. Self holding Switch Units, located on vertical support Rods in proximity to the Centre Tube and
positioned by Clamp Screws, have 2 pairs of contacts operated with a snap action and held by repulsion between the secondary and Tertiary Magnets ofthe Switch Unit Assembly.

Adjustments:
The Switch Head incorporates two/three/Four sets of Switch Units and “Differential” in operation between the sets are adjustable.
