Types of Pressure Contact Switches and Applications

Vacuum Switches: Found in vacuum systems and applications where pressure needs to be monitored or controlled. Applications include medical equipment and semiconductor manufacturing.

Differential Pressure Switches: Ubiquitous in HVAC systems to monitor and control air or fluid flow by sensing changes in pressure between two points.

Air Pressure Switches: Found in pneumatic systems and applications where pressure of air needs to be monitored or controlled, including HVAC systems and air compressors.

Hydraulic Pressure Switches: Used in hydraulic systems to monitor and control pressure levels in many industrial and mobile equipment operations.

Float Switches: Employed in liquid-level control applications, such as sump pumps, water tanks, and industrial fluid handling systems.

Piezoelectric Pressure Switches: Used in applications where a rapid response to pressure changes is called for, like medical devices and certain industrial processes.

Snap-action Switches: Typical in control panels and appliances, giving a quick and reliable response to pressure or position changes.

Hermetically Sealed Pressure Switches: Good for applications where the switch needs to operate in harsh environments or involves corrosive substances, like in chemical processing or aerospace industries.

Microswitches: Widely used in control systems, appliances, and automation devices where precise and small movements need to be detected.

Limit Switches: Employed in manufacturing and automation processes to detect the presence or absence of an object, control machinery movement, and provide position feedback.

Knowing the specific characteristics and applications of each switch is important for selecting the right switch for your electrical system.

How to Select a Pressure Contact Switch

Application Requirements: Understand specific requirements of the application where your pressure contact switch will be used. Consider factors like voltage ratings, current capacity, and environmental conditions. Do you need a switch with ground fault protection or shunt trip features for remote operation? Asking these questions will help in choosing a switch compatible with your intended use.

Compatibility with Existing Equipment: Check the compatibility of the pressure contact switch with the existing electrical equipment. Ensure that it integrates seamlessly with the current setup to avoid compatibility issues and malfunctions.

Reliability and Quality: Assess the reliability and quality of the pressure contact switch, whether it is new, refurbished, or surplus. Consider factors such as the manufacturer's reputation, product certifications, and warranty options to help the longevity and performance of the switch.

Budget Constraints: Evaluate the budget constraints of your project and provide options in line with your financial situation. Compare costs of new, refurbished, and surplus pressure contact switches, taking into account the overall value, including reliability and performance.

Regulatory Compliance: Ensure that the pressure contact switch meets relevant industry standards and regulatory requirements. Compliance with safety standards is important for preventing accidents. Employee safety and legal regulations should be top priority. Confirm the selected switch meets necessary certifications and standards for your industry application.

Below are common Amperage and Voltage combinations of pressure contact switches for various applications. All are available with Ground Fault and Shunt Trip features.
