In the world of electronic components, the terms ‘tactile switch’ and ‘push button switch’ are often heard, but understanding their differences and specific uses can be confusing. Here, we delve into the nuances of these two popular types of switches.
1. What Are Push Button Switches? Push button switches are mechanical switches used to control the flow of electric current in an electronic circuit. When pressed, they either make or break an electrical connection, allowing or interrupting the flow of electricity through the circuit. These switches are versatile and come in various shapes and sizes, tailored for different applications.
Types and Functionality Push button switches are broadly categorized into two types:
- Momentary: These switches connect or disconnect the circuit only while being pressed. Upon release, the circuit returns to its original state.
- Latching: These have two stable states. The switch remains in its new state until pressed again, either maintaining an open or closed circuit.
Applications and Advantages Push button switches are intuitive and easy to operate, often customized to suit specific applications. They are durable, designed for a large number of actuations, and in many cases, incorporate visual indicators like LEDs.
However, they are typically designed for simpler on/off control and may not suit applications requiring variable control.

2. What Are Tactile Switches?
Tactile switches are designed to provide feedback upon actuation. When pressed, they offer a noticeable ‘click’ or resistance, assuring the user that the switch has been activated. This tactile feedback is crucial in applications where precise control is necessary, helping to prevent accidental presses.
- Momentary Action: Like momentary push button switches, tactile switches make or break connections only while pressed.
- Design and Use: They are typically smaller and used in low-power, low-voltage applications like remote controls or keyboards.
Comparing Tactile and Push Button Switches While both are mechanical switches used for controlling electrical circuits, their design, functionality, and tactile feedback differ significantly. Push button switches can vary in their tactile response, with some offering a click similar to tactile switches, while others have a smoother, quieter actuation.
3. Choosing the Right Switch Selecting between a tactile switch and a push-button switch depends on the specific needs of your application. For high-precision, low-voltage environments where feedback is crucial, tactile switches are ideal. On the other hand, push button switches are better suited for more straightforward on/off applications and can be used in a wider range of environments due to their varying designs and functionalities.
In conclusion, both tactile and push-button switches play vital roles in electronic circuits. Understanding their differences and applications ensures the right choice for your specific needs, enhancing both functionality and user experience
