In these air compressor switches, once the motor driver is switched off at cut-off pressure, the compression pump stops leaving the pistons frozen in their positions within the cylinders. Understanding how these air compressor switches work is vital because of their significant reliance on the unloader valve. Air compressor switches with positive displacement pumps use piston movements to compress air to give rise to pressure. Positive displacement compressor pumps are also called reciprocating compressor pumps. How the Air Compressor Switch in a Positive Displacement Air Compressor Pump Works
Though rare, any malfunction in your compressor switch may pose a danger. Remember to watch for any malfunction, such as leakages in your air compressor switch. This cycle goes on for as long as you use the compressor to supply the required pressure for your tools. The motor subsequently restarts, allowing more air into the compressor tank until the cut-out pressure is hit again. This action of the diaphragm brings about contact and completes the circuit.
When the air pressure in the compressor tank drops and hits the cut-in pressure, the diaphragm deforms in the opposite direction. The diaphragm will remain distorted as long as the pressure in the air compressor tank remains at a particular volume called the differential. Deformation of the diaphragm forces the compressor switch to break contact, turning off the motor leaving the tank with enough pressure. This pressure causes the diaphragm in the air compressor switch to deform. When you switch on your air compressor, the pressure inside the tank increases until it reaches the preset cut-out pressure. Now that you understand what makes up an air compressor switch, let’s analyze the process of how the switch functions in a compressor: The unloader may be located either on the side or bottom of the switch. When the air compressor switches trips, the unloader valve relieves any pressure that might be trapped between the check valve and the pump. If you set the lever to auto function, the compressor switch will turn on and off depending on the cut-in and cut-out pressure you set before. The auto/off lever is a lever or knob that toggles the air compressor switch to turn off automatically when the cut-out pressure is reached. This means that the adjustment springs play a vital role in maintaining a constant differential in your compressor. Loosening the adjustment spring makes the diaphragm require less air pressure to flex and turn the air compressor’s motor off. Tightening the adjustment springs in an air compressor switch makes the diaphragm need more pressure to turn the air compressor off. The differential is the range between the cut-in and cut-out pressure. On the other hand, cut-in pressure is the minimum pressure that activates the air compressor switch to turn on. Cut-out pressure is the highest valve that triggers the air compressor switch to break contact and turn off the motor. Let’s quickly define cut-in and cut-out pressure. The spring adjusts the cut-in and cut-out pressure in the compressor switch. It functions to relieve the pressure between the check valve and the pump. This valve is located at the base of the pressure switch. All this happens to control the differential of the air compressor that we will discuss ahead. 
Likewise, when the diaphragm separates the contact, the driver shuts down. The circuit is complete when the contacts touch and the driver is powered on. Contacts are made from a conductive material such as metallic strips. The contacts are two points in the air compressor switch that make or break the connection to complete or disconnect the circuit. This diaphragm’s movement up and down causes the contacts to separate and touch accordingly. The rubber membrane is pushed up or down depending on the pressure within the compressor. Every switch comprises the following components: The DiaphragmĪlso called the membrane, the diaphragm is made up of flexible material that changes according to the pressure levels inside the tanks. The compressor switch looks like a rectangular housing that contains several parts inside it that work together for the basic working of the switch. Components of An Air Compressor Pressure Switch
