▷【Easy to Control】 ：The reed switch normally open is a passive electronic switch contact component, with a simple structure, small size, easy to control and so on
▷【For Magnetic Field】： As a signal for controlling the magnetic field line switching device, the reed switch normally open can be used as a counter, and it is also widely used in various communication devices
▷【Effective & Functional】：The reed switch normally open is clean, the waveform is good, and the driving capacity is greater than 15mA. The output form is a digital switch output (0 and 1) with fixed bolt holes. The PCB board is small in size for easy installation
▷【Wide Application】: Wide voltage comparator LM393 is used in SPC exchange, copier, washing machine, refrigerator, camera, disinfection cabinet, door magnet, magnetic window, electromagnetic relay, electronic scale, level meter, gas meter, water meter, etc
▷【Usage Principle】： Generally, two glass tubes made of special material reeds are separated. When the magnetic substance is close to the glass tube, under the action of the magnetic field lines, the two reed tubes are magnetized and attract the contacts to each other, and the reeds will be pulled together, so that the circuit of the connection node communicates. After the external magnetic force disappears
