Which component moves the contact assemblies between Source 1 And Source 2?

• A. Solenoid
• B. Relay coil
• C. Linear Actuator
• D. Switch

Answer: (C)

The mechanism that physically shifts the contact assemblies from one source to another must provide straight-line motion with enough force and control to reposition the entire contact bank. A linear actuator delivers precisely that: it converts electrical energy into steady, linear displacement, enabling the contact assemblies to move along a straight path between Source 1 and Source 2 and lock into the correct position. Solenoids can produce motion, but typically only a short stroke and with less control for large, high-force moving parts. A relay coil actuates a relatively small internal contact, not the large contact assemblies that switch between two power sources. A switch is the contact surface itself, not the device that moves it. So the component best suited to move the contact assemblies between two sources is the linear actuator.
