In remote control switching systems, the line voltage contact armature is moved to the ON position by a split low-voltage coil. Which option is correct?

In remote control switching systems, the line voltage contact armature is moved to the ON position by a split low-voltage coil. Which option is correct?

• A. False
• B. Only for DC systems
• C. True
• D. Not used in control circuits

Answer: (C)

A low-voltage control coil is used to operate the line-side contacts in a remote control switch. When the coil is energized, it creates a magnetic force that pulls the armature, closing the line contacts and turning the circuit ON. The term split coil simply refers to how the coil is arranged to be energized from a control source, but the essential function remains: a low-voltage coil moves the armature to connect the high-voltage path. So, this is true because the control action is accomplished by energizing a small coil to move the larger, line-voltage contacts. It’s not limited to DC systems, and it is indeed used in control circuits.
