Inductive load must be added with absorption circuit The dry reed disconnects the inductance (coil, relay) to generate high voltage back EMF and break down the contact; parallel freewheeling diode/RC snubber circuit. It is strictly prohibited to exceed the contact current, and the ordinary relay is added in the middle of the high-power load to expand the capacity. Magnet placement: parallel/vertical two trigger modes, distance affects sensitivity; avoid mutual interference of multiple magnetic fields High-voltage use scenario: to ensure the creepage distance of the pin, select the high-voltage reed switch, and do not replace it with the small signal switch. Avoid strong impact and vibration, and install additional buffer gaskets to prevent false closing and contact bounce.
