Mini Float Level Switch

PRODUCT INTRODUCTION The reed switch relies on two basic scientific principles namely: buoyancy and magnetism. Buoyancy causes the float (which contains a magnet) to rise with the liquid and magnetism helps open and close the switch. Since this product's this product has been introduced to the market, it has seen significant improvement and advances with regards to convenience, safety and lowering costs. Fig. 1 illustrates the pivot activation (FCH Type reed switch). When float's magnet is moved close to the switch's stationary stem, the float magnet pushes the stem's switch circuit...

REED SWITCH PROTECTION When using reed switches for inductive loads such as motors, relay coil, solenoids, etc., the contact points will sometimes be subjected to high voltages. Such high induced voltages may damage the reed switch or significantly reduce its life. H Therefore, circuit protectors such as: RC snubbers, varistors or clamping diodes are recommended. (see Fig. 4a, Fig. 4b, Fig. 4c) 4 Do not directly connect the solenoid valve,motor 4 CAPACITIVE LOADS When using reed switches for capacitive loads such as capacitors, incandescent lamps or long cables, the contact points will be...
