Best Well Pump Pressure Switches:
The pressure switch is one of the most common types of well pump switches. This type of switch operates by making or breaking electrical contact depending upon the water pressure.
The switch activates when the water pressure reaches a predetermined point to either break or create an electrical circuit.
After the pressure drops or increases, the switches turn on again and activate the circuit.

How to Choose a Pressure Switch for Your Well Pump?
To ensure that your well pump works well, it is essential to verify all specifications before you buy a pressure switch. There are many options on the market, but they all come in two types: solid-state or electronic.
Most mechanical pressure switches have a sensing element and an electrical snap-action switch.
Although manufacturers may employ several types of sensing elements, they all share one thing: They must respond quickly to changes in pressure. They act on the switches’ contacts by closing and opening them.
Solid-state switches have a metal diaphragm that is nearly the same size as a dime. The manufacturer edges the micro strain gauge onto the metal diaphragm. An increase in pressure will alter the strain gauge’s resistance.
The inbuilt digital comparator monitors the output of the strain gauge and compares it with user-specified setpoints. The electronic circuits of the strain gauge switch on the solid-state relay to complete the circuit when the pressure reaches a certain point.
These are the Specifications to Consider When Making A Selection
You can choose a pressure switch that works appropriately by knowing the requirements of the well pump you wish to control. These are the specifications that you should consider when selecting a pressure switch for your well-pump.
You can read the descriptions for each specification to help you understand and decide the best range for your well-pump.
The pressure range indicates the pressure at which the valve operates. The pressure that your application creates for the valve must be within the designated numbers to prevent any problems. You cannot adjust the fixed setting of some switches made by manufacturers.
Many well pumps can use pressure switches with an adjustable range. Ensure that you know exactly what you require before making a purchase.
Horsepower to Voltage
The horsepower ratio to voltage is the limit on the horsepower that the pressure switch can transfer from your well pump to which it controls, regardless of whether the power supply is single-phase or three-phase.
It would help if you verified the power specs and horsepower of the pump before you purchase a pressure switch. This will ensure that you can trust the well pump to work with the pressure switch.
The pressure switch does not react to movement in the differential range. Instead of reacting to pressure gradually falling to the contacts, the pressure switch only reacts when the pressure drops to the setpoint. This causes fast snapping action to contactors and activates the controlled point.
Depending on which pressure switch you choose, the differential range can be adjusted or fixed.
The maximum pressure that your pressure switch can handle is called burst pressure. The pressure that exceeds the burst pressure can cause the mechanically controlled parts and inner seals to fail or become unusable. To prevent damage or failure to the pressure switch, the pressure in your application must be below the burst pressure.
A few well pump pressure switches include a manual switch to control OFF/ON/AUTO and an unloader connection for the air compressor valve. Other special features include multiple pole contacts or high- or low-pressure cutoffs.
Consider the application requirements when choosing a special feature. These requirements can include both types and sizes.
