110V Wired Door Magnetic Contact Switch (1 Set) - Home Security Alarm System for Doors & Windows - Perfect for Smart Homes, Offices, and Storage Security

I purchased 3 sets of these switches as a test. They are being used to turn on lighting in closets and the pantry. I'm using box-store LED tube lights. 18" and 24" (12 watt load on the 24"). They work great and are consistent in their operation. Sort of an "Open and Shut" case.You do need a clear familiarity of home wiring accessories to negotiate the installation. Splicing, insulating, perhaps adding an plug as well, depending on existing conditions.I used Scotch double stick tape initially for the first install but have since secured the switches with small screws. There is a fair amount of mounting options and leeway for proper operation. Pretty forgiving IMO.
