True or False: Remote control switching systems employ a split low-voltage coil to move the line voltage contact armature to the ON (latched) position.

• A. True
• B. False
• C. Not sure
• D. Cannot be determined

Answer: (A)

Remote control switching relies on a low-voltage control coil to actuate a higher-voltage line-side switch. A split or dual-coil arrangement is a common way to achieve a latched condition: energizing one coil moves the line-voltage contact armature to the ON position and, once in that position, the armature is held there without continued control current. To turn it OFF, a separate pulse or the opposite coil is used. This setup keeps the control power small while the contacts carry the higher line voltage, and the latched ON state remains even after the control signal is removed. So using a split low-voltage coil to move the armature to the ON (latched) position is a characteristic feature of many remote control switching systems.
