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. Not sure
• C. Cannot be determined
• D. False

Answer: (A)

Remote control switching relies on a low-voltage control circuit to operate a relay that switches the higher line voltage. In latched, remote-controlled relays, a split low-voltage coil arrangement—two coils on the same core (set and reset)—allows the armature to move to the ON position and then be held there without continuous control power. Energizing the set coil moves the contact armature to connect the line voltage circuit, and the magnetic latch keeps it in that position after the control signal is removed. A reset coil can later demagnetize and return the armature to OFF. This setup protects the control circuit from high voltages while reliably maintaining the chosen state, which is why the statement is true.
