For example, in the pipeline to install an accumulator (simply use a gas or no leakage of the tank better, when the pump work when the gas is compressed. When the water gradually inflated, to ensure that the motor Again when the normal operation of the pressure). So that you can achieve your request.
Since the pump motor to start to normal operation is the time, not the reason for the switch, then any switch can not meet the requirements you say, can only think of another way.
Because the water is incompressible, as long as no water, the pressure will immediately reach the pressure switch set value. So the pump will stop. When the water, the same is because the water is incompressible, the pressure immediately removed, lower than the pressure switch set value, so the pump began to run. But it takes time to run up, so you will find a pause.
