on video 3 phase motor DOL starter control wiring with float switch diagram

 DOL starter,A DOL starter is Direct On Line starter or across the line starter is a method  of starting of a 3 phase induction motor. in dol starter an induction motor is connected directly across its  3 phase supply and the dol starter applies the full line voltage to the motor terminals.

what is float switch?

float switch is a type of level sensor a device used to detect the level of liquid within a tank. The switch may be used to control a pump as an indicator an alarm or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

how does a float switch works?

float switch is a type of level sensor a device used to detect the level liquid within a tank. one pattern uses a reed switch mounted in a tube a float containing a magnet surrounds the tube and is guided by it. when the float raises the magnet to the reed switch it closes.

Magnetic contactor 

Magnetic contactro are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from on and off state. magnetic contactor act as a safeguard to protect the power supply and the motor.
