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

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

Answer: (A)

Remote control switching commonly uses a low-voltage coil to actuate a relay that controls line-voltage contacts. To keep the line circuit in the ON position without continuous power, a split (dual) low-voltage coil arrangement is used. Energizing the appropriate coil moves the armature to engage the line contacts and, with the latching design, holds that position after the control current stops. A separate coil can then be energized to release and return the armature to the OFF position. This latching capability is why remote control systems can reliably stay on or off with only momentary control signals, keeping the high-current line circuit sealed and stable.
