2．Types of 4-pin toggle switches
A 4-pin toggle switch is an electronic component commonly used to control circuit switching. Depending on different classification standards, 4-pin toggle switches can be divided into several common types:
Locking 4-pin toggle switch: This type of toggle switch requires the button to be pressed and rotated to turn on or off the circuit. They are usually used in circuits that need to avoid accidental shutdown.
Momentary 4-pin toggle switch: This type of toggle switch will bounce back after being pressed and will automatically return to its original position when the button is released. They are usually used in circuits that require frequent on-off switching.
Latching 4-pin toggle switch: This type of toggle switch will remain in the pressed position until it is pressed again to release it. They are usually used in circuits that require a specific position to be maintained.
Spring return 4-pin toggle switch: This type of toggle switch will only remain in the pressed position briefly and will immediately return to its original position when released. They are usually used in circuits that require a brief trigger.
Toggle switches generally have the option of being either through-hole or screw-mounted. Through-hole and screw-mounted are both forms of electrical components used for fixing and connecting circuits.
Through-hole is an electrical component that is fixed and connected to a circuit board by inserting pins into holes on the board. They are typically available in single-row, double-row, and triple-row configurations. Through-hole pins are fixed and connected to the circuit board through friction and pressure, and are characterized by their easy installation and reliable connection.
The advantages of through-hole pins are their simple installation and reliable connection, making them suitable for applications that require easy installation, small size, and frequent connections. The disadvantage of through-hole pins is that the connection strength is weaker and more prone to loosening, making them unsuitable for applications that require high connection strength. Additionally, since through-hole pins need to be inserted into holes, they cannot be directly fixed to the circuit board and require other methods of fastening.
Screw-mounted toggle switches are electrical components that are fixed to a circuit board using screws. They are available in a variety of types, including round head, flat head, and semi-circular head. Screw-mounted toggle switches are fixed to the circuit board using screws, making them easy to replace, disassemble, and repair as needed.
The advantages of screw-mounted toggle switches are their strong connection, replaceability, and ease of disassembly, making them suitable for applications that require reliable connections and easy replacement. The disadvantage of screw-mounted toggle switches is that installation and disassembly require tools such as screwdrivers, making them relatively more complicated to use than through-hole pins.
