There are different types of pressure switches, designed to adapt to specific industrial applications. Mechanical pressure switches activate an electrical contact through a diaphragm or a piston when the pressure reaches the preset value, making them suitable for hydraulic and pneumatic systems. Electronic pressure switches and digital pressure switches use advanced sensors for more precise pressure control and offer a programmable interface for configuring operating parameters, making them ideal for automated applications. Adjustable mechanical pressure switches allow the intervention value to be modified directly on the device using adjustment screws or graduated knobs, adapting to hydraulic systems, water pressure switches, oil pressure switches, and industrial circuits. Differential pressure switches measure the pressure variation between two points and are used for monitoring filters and HVAC systems. Elettrotec is one of the leading manufacturers of mechanical pressure switches and differential pressure switches, providing tailor-made solutions for high-precision systems and complex applications.
