2 PRODUCT INTRODUCTION 4 INTRODUCTION 4 PRIIPE Since technologies of the product have more and more advance, the products need comply with a requirement for more convenient, safe and low cost. The float switches are extremely compact, simple and are easy to install on any small space. These switches are not effected by electrical interference. They can withstand to chemicals, high temperatures and pressures if the correct material of float switch is selected by the customers. Fig. illustrates the method of pivot actuation (such as the FCH TYPE float switches). When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch "snaps" the contact together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch does not touch. The circuit is open. 4 IQUID PROPERTIES AND FOATS When the liquid specific gravity is less or more than the water, the float on the switch will either increase or decrease the iersion depth. The switch actuation level will also change. All actuation levels are assumed with the water (SG=). If your liquid has a different specific gravity, you should not specify the float specific gravity more than liquid, that will not cause the float rise with the liquid level. The reed switch inside the stationary stem will not be activated by the magnet inside the float. If your liquid has a high viscosity, you should specify largest size float that will provide a greatest buoyant force to ensure the units operate normally. Because the float switches are activated by the magnetic field of permanent magnet inside the float, make sure the liquid is no iron powder or magnetic material to avoid magnetic interference. closed S N magnet open (Fig. ) Fig. 2 illustrates the method of perpendicular actuation (such as the FC V TYPE float switches). When the magnetic field of ring magnet inside the float is moved into the proximity of reed switch inside the stationary stem, the reed switch "snaps" the contact together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch does not touch. The circuit is open.

3 REED SWITCH PROTECTION 4 INDUCTIVE OADS When using reed switches for inductive loads such as motors, relay coil, solenoids, etc., the contacts will be subjected to high induced voltages during opening of the contacts (load circuit). Such high induced voltages (transients) may cause damage to the reed switch or significantly reduce its life. Therefore, protective circuits such as: RC (snubber), varistor or clamping diodes are recoended. (see Fig. 4a, Fig. 4b, Fig. 4c) 2 C= I (uf) 0 R= E E 0I(+ 0 ) H AC C N R (RC) 4 It is prohibited to drive directly solenoid valve, Fig. 4 (a) motor or magnetic switch. H F AC DC G N (Varistor) (Diode) Fig. 4 (b) Fig. 4 (c) 4 CAPACITIVE OADS When using reed switches for capacitive loads such as capacitors, incandescent lamps or long cables, the contacts will be subjects to high surge (inrush) current. Therefore, protective circuits such as: surge suppressors or current limiting resistors are recoended. (Fig. a, Fig. b) C R E(V) R E(V) Fig. (a) Fig. (b) Telefon: Telefax:
