Operation
The Type W-2 Switch is a rotary roller action switch. Rotation of the shaft causes the spring
loaded rotor rollers to move from one set of stationary contacts to another. The number of
roller contacts can vary from 1 to 6. On standard potential contacts, an insulated wheel is used
on both ends of the roller contact that rolls inside the stator frame.
Contact Terminals
