Why magnetic switch is better than micro switch?
The traditional mechanical plunger micro switch has to be installed accurately for the door panel or bracket push the rod on the switch, it has wear and tear issue for long time use. The 110VAC high voltage directly applies on the micro switch will cause sparks inside the micro switch which lower the life of usage too.
The magnetic switch is much easier for installation, no restriction on the types of the door or windows. 12VDC low voltage on the magnetic switch connection is much safer. And no mechanical touch for longer usage.
