Two wire magnetic switches cannot be short circuited to power. Magnetic switches, whether mechanical or electronic, have very low resistance, similar to wires. Directly connecting them to a power source can cause a short circuit, and overload currents in the circuit can damage the magnetic switch, causing the contacts to melt and close normally or burn out directly. Magnetic switches cannot be directly connected to large inductive components (such as motors, large capacity solenoid valves, etc.). Excessive inductance can generate a large amount of surge current and burn out the magnetic switch when the circuit is turned on or off. When using magnetic switches, it is necessary to ensure stable and interference free current or voltage. As a magnetic sensitive component, magnetic switches should be used in environments without strong magnetism or large amounts of iron filings. Otherwise, the magnetic sensitivity performance of the magnetic switch will decrease, leading to misoperation or non operation, and reduced lifespan. If strong magnetism is necessary, magnetic switches suitable for strong magnetic field applications should be selected. Two wire electronic magnetic switches have a certain leakage current, and it is necessary to ensure that the starting current is much greater than the leakage current during use, otherwise it may cause misoperation. Three wire electronic magnetic switches can effectively improve by controlling the leakage current to be small, or choose mechanical magnetic switches without leakage current.
