A push button switch is a simple type of switch consisting of a simple electrical mechanism that controls the action of a machine or turns something on or off. These buttons are mostly made of plastic or metal, and the shape of the button can fit your finger or hand for easy operation, or it can just be flat.
Types of Push Button Switches:
There are many different types, each with unique benefits. It is crucial to choose the type that suits your specific application.
Common types include:
- 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
How do they operate?
The actuator and contact are the specific parts of the pushbutton switches.
The actuator will pass through the switch into a thin cylinder at the bottom. Inside, there is a movable contact and a spring. When the actuator is pressed, it touches the fixed contacts, activating the device.
Pushing buttons can be used as a normally open or normally closed contact which modifies the condition when the actuator works. In the momentary switch, you should keep the button to keep the user from taking measurements. Then when the button is released, this task is reset. Hold the switch to hold the switch until the locking button is pressed again.
Voltage Ratings:
The specific differences between AC and DC capacities are usually clearly highlighted in switches. You should avoid assuming a pushbutton switch is adequate if the current rating does not exceed the maximum load of the circuit.
The required circuit-breaking speed depends on an AC or DC connection. Depending on the switching of inductive or resistive loads and their suitability, the characteristics of the electrical load must also be considered.
Typical Applications:
Push button switches can turn a machine on and off or cause a device to perform a specific task, as in the case of 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.
They are famous for a variety of applications, including:
- A calculator,
- push button telephone,
- household appliances,
- Office and industrial applications.
