Which of the following is a type of switch commonly used for remote control in lighting strategies?

• A. PIR occupancy detector
• B. Remote controlled switches
• C. Dimmable driver
• D. Photoelectric sensor

Answer: (B)

Remote controlled switches provide wireless on/off control of a lighting circuit, making them the typical choice for remote operation in lighting strategies. They are designed to receive signals from a remote or a control hub and act quickly to switch lights from a distance or as part of a broader automation system. This capability is what makes them stand out when the goal is remote operability, scene control, and coordinated lighting.

The other devices are sensors or drivers with different roles. A PIR occupancy detector senses presence to automatically turn lights on or off, but it isn’t a switch you operate remotely. A dimmable driver changes brightness levels but doesn’t itself provide remote actuation. A photoelectric sensor reacts to ambient daylight to adjust lighting to save energy, not to enable remote control.
