Circuit protection of float switch
Circuit protection of float switch
| 1. When the float switch is used in the inductive load circuit of motor, relay and |
| solenoid coil,it is suggested to add shunt circuit to protect the two sides of the |
| load, for example: relay, RC (buffer), rheostat and diode etc. |
| Note: DO NOT connect the flow switch directly with electromagnetic valve,motor and |
| electromagnetic switch. |
| 2. When the float switch is used in capacitive load circuit of capacitance, |
| long cable, there is a upsurge current in contact of switch;it is suggested |
| to add shunt circuit to protect the two sides of float switch, such as limiting |
| resistor or surge absorber . |
