Many push button types exist, according to their functions and design features. The common push button switch types will be introduced in detail below and show some applications of push buttons.
Push Button Types by Working Mode
According to the working mode of push-button switches, they can be divided into two types: momentary push-button switches and maintained push-button switches. Both types of push-button switches are widely used in electrical control systems and electronic equipment.
Momentary Push Button Switch: This kind of push button switch has a contact that closes when pressed and opens immediately after being released. It is used in scenarios that require a short-term power supply, such as the start button of electronic equipment and the trigger button of an alarm. wait.
Maintained Push Button Switch: The contacts are closed when the button is pressed, and remain closed after the button is released until the contacts are opened when the button is pressed again. It is often used in control scenarios that require continuous power or locked status, such as switch buttons for lighting, power switches of electronic equipment, etc.
Push Button Types by Materials
Plastic push buttons, metal push buttons, and stainless steel push button switches are classified based on the materials used in their construction. Each type has distinct characteristics and is chosen according to the application’s specific requirements, including factors like durability, environmental conditions, and aesthetic preferences.
Plastic Push Button Switch: This is mainly made of plastic. It is lightweight and has good insulation. It is suitable for general household appliances, toys, and other scenarios.
Metal Push Button Switch: this is durable and beautiful. It is suitable for equipment that requires durability and aesthetics, such as automotive electronic equipment, industrial control panels, etc.
Stainless Steel Push Button Switch: has the characteristics of corrosion resistance and high-temperature resistance, and is suitable for equipment in special environments, such as food processing equipment, medical equipment, etc.
Push Button Types by Circuits or Poles
Single pole push button, double pole push button, and 3 pole push button switches are classified based on the number of poles they have. This classification helps determine the switching capabilities and applications where these switches are most suitable, ranging from simple on/off control to more complex circuit coordination requirements.
Single Pole Push Button: This push button switch has only one electrical contact and is suitable for simple control scenarios, such as single light control, single motor start and stop, etc.
Double Pole Push Button: Double Pole Push Button has two electrical contacts, which can realize more complex control functions, such as dual light control, dual motor start and stop, etc.
Three-pole push button switch: The three-pole push button switch has three electrical contacts and is suitable for scenarios requiring multi-channel or interlocking protection, such as electrical cabinet control, multi-function control of mechanical equipment, etc.
Push button types by the number of electrical terminals
2 terminal push button switches, 3 terminal push button switches, and 4 terminal push button switches are classified based on the number of terminals they have. These terminals determine the switch’s functionality, such as the type and number of circuits it can control, making them suitable for various electrical and electronic control applications ranging from simple to complex.
2 Terminal Push Button Switch: This push button switch has only two electrical connection terminals and is suitable for simple circuit control, such as normally closed buttons, normally open buttons, etc.
3 Terminal Push Button Switch: The three-terminal push button switch has three electrical connection terminals, which can realize more flexible circuit wiring methods, such as dual control buttons, hold buttons, etc.
4 Terminal Push Button Switch: The four-terminal push button switch has four electrical connection terminals and is suitable for more complex circuit wiring requirements, such as dual-control holding buttons, time-sharing control buttons, etc.
Examples of applications for push button switches
Household appliance field: Plastic momentary push button switches are often used as buttons on TV remote controls, start buttons on microwave ovens, etc.
Industrial control system: Metal retention button switches are suitable for start and stop control of mechanical equipment, operation of automated production lines, etc.
Automotive electronic equipment: Stainless steel bipolar push button switches are suitable for interior control panels, such as car light control, air conditioning control, etc.
Through the detailed introduction of different types of push-button switches and examples of application scenarios, readers can more fully understand the role and selection principles of push button switches in various fields, thereby providing reference and guidance for actual circuit design and control operations. As an indispensable part of the electronic control field, the selection and application of push button switches will have an important impact on the function and performance of the equipment.
