Types of Switch
The switches produced by our company mainly include the following types:
Pressure Switch
Pressure switch is a device that detects and responds to changes in pressure within a system by either opening or closing an electrical circuit. It acts as a control mechanism, automatically starting or stopping equipment based on preset pressure levels.
Oil Level Switch
Oil level switch is a safety device used in engines and compressors to monitor the oil level within the crankcase. It triggers an alarm or shuts down the engine if the oil level drops below a predetermined level. This prevents damage to the engine or compressor due to low oil.
Features of Switch
Automatic control
It automatically executes the switch action according to the pressure change without manual intervention, improving the system efficiency.
Adjustable setting range
Most pressure switches support custom pressure thresholds (such as on/off pressure) to meet the requirements of different scenarios.
High precision and stability
Precision springs, diaphragms or electronic sensors are adopted to ensure sensitive response and long-term reliability.
Strong durability
The shell is mostly made of metal or high-strength plastic, which can withstand high temperatures, corrosion or vibration environments.
Diverse types
It is divided into mechanical type (pure mechanical structure) and electronic type (with digital display and signal output), meeting different needs.
Safety protection
Some models are equipped with explosion-proof and waterproof (IP rating) functions, making them suitable for hazardous or humid environments.
Applications of Switch
Industrial equipment
Pressure protection for air compressors, overload protection for hydraulic systems.
01
Refrigeration/air conditioning
Monitor the refrigerant pressure to prevent damage to the compressor.
02
Water treatment system
Control the start and stop of the water pump to maintain stable water pressure.
03
Pneumatic control
Adjust the working pressure of the cylinder or valve.
04
Safety alarm
When the boiler pressure exceeds the limit, it will trigger the shutdown or alarm.
05
Main Components of Switch
Diaphragm
A diaphragm is used to detect pressure. The material is usually pliable and sensitive to pressure.
01
Spring
Used in adjusting setpoints or cut-out points.
02
Lever
Used to activate or deactivate the switch.
03
Electrical contacts
Permit current to pass through them from an external power source.
04
Terminals
To connect the external power source to the contacts.
05
Switch Installation Steps
Select the installation point: Choose a point on the piping system where the pressure switch can be easily accessed for maintenance and where it will accurately measure the system pressure.
Prepare the threaded connection: If the pressure switch has a threaded connection, wrap Teflon tape around the threads in a clockwise direction to ensure a good seal. A
Gasket sealing: Stainless steel and copper gaskets are other common sealing methods for these pressure switches. These seals are available in flat or profile rings.
Install the pressure switch: Thread the pressure switch into the chosen installation point. Hand-tighten the switch and then use an adjustable wrench to secure it in place.
Connect the electrical wiring: Refer to the manufacturer's wiring diagram before wiring a pressure switch. Typically, there will be two or three terminals: one for the power supply, one for the load, and possibly a ground terminal.
Set the pressure limits: Adjust the high and low pressure limits according to the system's requirements. This is usually done by turning adjustment screws on the switch.
Test the pressure switch: Once the pressure switch is installed and wired, slowly re-pressurize the system and check for leaks around the switch.
Secure the pressure switch: If the switch is not already mounted, secure it to a wall or panel to prevent movement, which could lead to wiring damage or inaccurate pressure readings.
Final inspection: Perform a final inspection to ensure that all connections are secure and that there are no leaks. Verify that the electrical connections are properly insulated and that the switch operates as intended.
Document the installation: Record the installation details, including the pressure switch model, settings, and date of installation, for future reference and maintenance.
