What is the Difference between a Mechanical Switch and an Electrical Switch?
Mechanical switches and electronic switches are two different types of switching devices. There are some differences in their working principles and characteristics. The following are common differences between them:
1. Working principle:
Mechanical switches work through physical mechanics to open or close circuits through mechanical contact.
Electronic switches control the on and off of circuits through electronic components (such as transistors, relays, integrated circuits, etc.).
2. Accuracy and stability:
Electronic switches usually have higher accuracy and stability. Because they are implemented by electronic components. This can reduce wear and failure problems caused by mechanical contact.
Mechanical switches may have problems such as poor contact, carbonization, and wear after long-term use.
3. Rated current and voltage:
Mechanical switches are usually used in low-voltage and low-current applications.
Electronic switches can handle higher voltage and current. Electronic switches can be driven by external circuits. It is suitable for various circuit control needs.
4. Switching speed:
Electronic switches usually have faster switching speeds because electronic components respond faster.
Mechanical switches may have longer mechanical movement times, resulting in slower switching speeds.
5. Life and reliability:
Mechanical switches involve mechanical contact and movement. Their life may be limited to a certain extent.
Electronic switches usually have longer life and better reliability.
6. Size and volume:
Electronic switches are usually smaller. It suitable for applications with limited space. Mechanical switches may be larger, especially in high-power or high-current applications.
Mechanical switches and electronic switches have their own advantages and applicable scenarios. It is necessary to comprehensively consider factors such as specific needs, circuit requirements, and environmental conditions.
Paddle Selection of Target Flow Switch:
In order for the switch to sense changes in flow, the flow plate must not contact the pipeline or any other device in the pipeline.
To check whether there is contact. You can remove the flow switch housing and press the main lever back and forth several times to feel whether there is any obstruction. If there is no obstruction, it proves that there is no contact.
The flow switch has a detachable flow plate. Different flow plates can be selected according to the actual installation status. If there is no flow plate of suitable length, a slightly longer flow plate can be trimmed.
However, the flow plate should not be installed too short. Too short will affect the sensitivity of the switch, and in severe cases, the switch will not work.
