General design and functional characteristics of micro switch
The 3-pin PCB micro switch on the monitoring equipment is a switch component used to trigger or control the functions of the monitoring equipment. The working principle of the micro switch is based on mechanical movement. By pressing a button, the state of the switch is changed, thereby controlling the connection or disconnection of the relevant circuit. This simple and reliable design makes micro switches widely used in various monitoring equipment to achieve manual control and trigger different functions.
The working principle of micro switches on monitoring equipment is relatively simple. They are mechanical switches that control the opening and closing of circuits through mechanical movement. Micro switches usually have 3 pins, including normally closed (NC), normally open (NO) and common (COM) pins. In the normally closed state, the circuit is closed, while in the normally open state, the circuit is open. The common pin is usually connected to the circuit of the monitoring device.
1. Triggering method
Micro switches usually work by push triggering, which means that when the switch button is pressed, an internal mechanism is triggered to change its circuit state (for example, from normally closed to normally open or vice versa). A microswitch contains a trigger button, spring, and electrical connections. Typically, the exterior of a micro switch is a button that, when pressed or released, triggers mechanical components inside the switch.
2. Circuit connection
This type of microswitch is typically connected to the circuit board of a monitoring device to trigger a specific function or operation. For example, it can be used to turn monitoring equipment on or off, switch modes, trigger alarms, etc. Micro switches can be in one of two states, normally closed or normally open, depending on the design. When the button is pressed, it triggers the robotic arm to move and change the state of the switch. If it is a normally closed switch, then pressing the button will cause the circuit to open and vice versa.
3. Safety and durability
The size and shape of the microswitch need to be adapted to the design of the monitoring device to ensure accurate mounting on the PCB and ensure a reliable connection. Considering that monitoring equipment may need to operate for long periods of time, microswitches often need to have a certain degree of durability to ensure long-term reliability. The button of the micro switch usually requires a certain triggering force to be pressed to avoid misoperation.
4. Electrical characteristics
The electrical characteristics of the microswitch, such as maximum current and voltage ratings, must match the requirements of the monitoring equipment. Micro switches are usually used for various functions of monitoring equipment, such as power control, mode switching, recording start and stop, alarm triggering, etc. Depending on the design and connection of the buttons, different control operations can be achieved. Some microswitches are waterproof or dustproof to ensure reliable operation in harsh environmental conditions.
This 3-pin PCB microswitch can be used in various monitoring devices, including security cameras, alarm systems, sensors, etc., to trigger different operations or events. When designing and selecting a microswitch, the specific needs and requirements of the device need to be taken into consideration to ensure its reliability and performance.
Application scenarios of micro switches
A microswitch is a small electronic switch commonly used to trigger or control the operation of a variety of electronic and mechanical devices. Their design features make them suitable for many different application scenarios. Buttons in electronic devices are Micro switches that are often used as buttons in electronic devices (such as TV remote controls, mobile phones, and computer keyboards) so that users can tap them to start, stop, or select different functions.
Micro switches are used in household appliances such as washing machines, microwave ovens, ovens, etc. to detect the status of doors or lids and ensure that they stop operating when open and start operating when closed. In cars and other vehicles, micro switches can be used indoors, sunroofs, seat adjusters, clutches, brake pedals, etc. to trigger different functions and operations of the vehicle. Microswitches are used in industrial automation to detect the status, position, or safety of machines. They can trigger the start and stop of equipment, position control of conveyor belts, position control of robotic arms, etc.
In medical equipment, microswitches can be used to trigger various operations, such as buttons on medical instruments, door status detection, etc. Microswitches are commonly used on the buttons of video game controllers to detect player input. Micro switches can be used in security systems, for example, to detect the status of doors or windows and trigger alarm systems.
In audio equipment, microswitches can be used for volume control, switch control, etc. Micro switches can be used in lighting systems, for example, to trigger light switches or dimming. Microswitches are used to trigger various functions of electronic toys, such as making sounds, moving parts, etc.
These are just some common application scenarios for microswitches, in fact, they can be used in many other fields and devices to meet various triggering and control needs. The small design and reliability of microswitches make them useful in many electronic and mechanical applications.
Common functions of micro switches in monitoring equipment
Microswitches can be used to control the power supply of monitoring equipment. When the user presses the button on the device, the micro switch can trigger the power to turn on or off, causing the monitoring device to enter or exit the working state. Monitoring equipment may have different working modes, such as day and night mode, motion detection mode, etc. Microswitches can be used to switch these modes to meet different monitoring needs.
For surveillance cameras or video cameras, micro switches can be used to start or stop the recording function. Users can press the switch to manually trigger recording, or it can be combined with the motion detection feature to automatically start recording when motion is detected. Some surveillance equipment, such as cameras, have adjustable focus or direction. Micro switches can be used to manually control focus or direction to enable users to adjust the monitoring range.
Monitoring equipment is often integrated with alarm systems so that alarms are triggered when abnormal events are detected. Microswitches can be used to manually trigger alarms, or as part of a sensor trigger, for example, pressing a button to trigger an emergency alarm. On a surveillance monitor or screen, microswitches can be used to adjust brightness, contrast, and other display settings for a clearer image.
Some monitoring devices are used for security or access control, and micro switches can be used to detect the status of doors or door locks to trigger corresponding actions, such as alarms or access control. Micro switches can be used to manually calibrate surveillance equipment, such as adjusting the horizontal or vertical position of a camera to ensure it is positioned correctly.
These are common functions and uses of microswitches in monitoring equipment. The design and placement of microswitches can vary depending on the specific monitoring equipment and application needs. They provide a convenient way for users to manually control different functions of the device, while also being used to automate operations to increase safety and efficiency.
