Push button switches are simple electrical switches designed to control the action of a machine or turn something on or off. As the name implies, pushbutton switches comprise a push button, allowing easy pressing by users. These buttons are mostly made of plastic or metal, with a shape that easily fits your finger. When the button is pressed, it completes the electrical connection, allowing current to flow through the switch and the connected circuit. Additionally, push button switches come in varied sizes and configurations to meet different needs in various settings.
Potential Benefits of Push Button Switches:
Push button switches offer various benefits to use, such as:
- They offer a convenient way of controlling and functioning various machines and systems by providing a fundamental user interface.
- They are easy to use and are safe.
- Versatile nature with pleasant aesthetics.
- Reliable and energy efficient.
- Provide feedback and confirmational information.
- They are compact, allowing easy integration in various electronics.
- They are cost-effective, reliable, and durable.
Types of Push Button Switches:
There are many push button switch types, each with unique benefits. It is crucial to choose the type that suits your specific application. The list of popular push button switch types includes:
- Miniature Push-Button Switches
- Push to Break Switches
- Push to Make Switches
- Momentary Push-Buttons
- Square Push-Button Switches
- Circuit Board Push-Button Switches
- Tactile Push-Button Switches
- Push-Buttons for Arduino
- 2-Position Push-Button Switches
- Dual Push-Button Switches
- Panel-Mounted Push-Button Switches
- Latching Push-Button Switches
- Industrial Push-Buttons
- Push to Make Door Switches
- Push-Button PCB Switches, and
- Locking Push-Button Switches
Momentary and Latching Push Button Switches:
Push button switches come in two configurations, including:
- Momentary Action Push Button Switches – Also called tactile switches, feature a momentary action, returning to their original position when the button is released. This feature is particularly beneficial for applications requiring a temporary connection, such as turning on a light or activating a device while the button is held down.
- Latching Action Push Button Switches – Some push button switches have a latching action, staying in the pressed position after being activated until they are pressed again to release the connection. These are often used for on/off switches in various devices.
Typical Applications of Push Button Switches:
Push button switches can turn a machine on and off or cause a device to perform a specific task, like a calculator. In some cases, the button may be connected via a mechanical linkage, especially for commercial and industrial applications. That is, pressing one button can release another. Push button switches find applications in a wide variety of devices and environments, including:
- Consumer Electronics
- Household Appliances
- Medical Devices
- Doorbells
- Security Systems
- Automotive Industry
- Control Panels
- Emergency Stop Buttons
- Traffic Signals
- Industrial Automation
- Audio and Musical Instruments
- Toys and Gaming Consoles.
