What is the Importance of Push Button Switch?

1. Introduction

Push button switches, a common sight in our everyday lives, are omnipresent in myriad devices from simple household gadgets to complex industrial machinery. Owing to their streamlined and effective design, they allow us to operate electrical circuits with the least effort, thus making them an integral part of modern technology. In the forthcoming discussion, we aim to highlight the importance of push button switches, explore their varied types and applications, and understand why they hold such a central role in daily as well as industrial scenarios.

The Application of Button Switches

2. What is a Push Button Switch?

A push button switch, as the name suggests, is an electrical switch that is activated by the simple act of pressing a button. Its fundamental task is to either create or break an electrical circuit, thus allowing or halting the passage of current. These switches usually consist of a button, a protective housing, and electrical contacts. On pressing the button, the contacts come together, forming a complete circuit. However, when the button is released, the circuit is interrupted again.

3. History of Push Button Switches

The rich lineage of push button switches spans over a century, having their origins in the early 1900s. Initially, they found use in rudimentary electrical devices, but there has been a significant transformation in their design and functionality over the years. Early iterations, despite being groundbreaking for their time, were often bulky and lacked in reliability. However, thanks to leaps in material technology and manufacturing methodologies, we now have at our disposal push button switches that are compact, durable, and extremely reliable, marking a stark contrast to their initial versions.

4. Types of Push Button Switches

There is a varied assortment of push button switches, each tailor-made for specific use cases:
  • Momentary vs. Latching:
    Momentary push button switches, true to their name, remain in their ‘on’ or ‘off’ state only whilst being pressed. The moment the pressure is lifted, they revert to their original state. Conversely, latching switches stay put in their current state until they are pressed again, enabling the change of state.
  • Illuminated vs. Non-Illuminated:
    Illuminated push button switches come with a built-in light source that signals their operational status, providing a visual aid to the user. Non-illuminated switches, on the other hand, do not have this feature.
    FILN can produce all kinds of LED pushbutton switches, the common ones are ring buttons with lights and power symbol buttons, in fact, we can also customize all kinds of buttons with different symbols, and the colors can also be produced as single-color, two-color and three-color pushbutton switches.
  • Single-Pole vs. Multi-Pole:
    Single-pole switches are crafted to control one circuit. However, multi-pole switches, with their ability to control multiple circuits at the same time, provide an added layer of versatility.
    Currently FILN has developed the 4NO-4NC switch, which allows one FILN switch to control four devices at the same time.
  • Emergency stop button switch:
    as the name suggests is the emergency stop button switch, some large industrial equipment need to be equipped with an emergency stop button switch in order to prevent the occurrence of danger, FILN developed a waterproof IP67 emergency button switch, which is relatively rare on the market. FILN also offers lighted emergency stop switches.
  • Ultra-thin tactile button switches:
    These types of button switches are much smaller in size compared to conventional ones, primarily designed for use in confined spaces. They feature a short-stroke tactile mechanism, which provides a better feel and operational experience.
    FILN has developed various wiring methods to cater to different installation environments, including pin switches that directly connect to the circuit board, connector button switches that can be plugged and unplugged with connectors, and wire-attached ultra-thin button switches with a certain level of waterproof capability.

5. How Push Button Switches Work

The mechanics behind the functioning of push button switches are fairly straightforward.

When the button is pressed, it forces a conductive element—typically metallic—to bridge the gap between the two contacts, thereby forming a complete electrical circuit. This action facilitates the flow of current through the switch, powering the device it’s connected to.

However, when the button is released, the contacts are disconnected, resulting in the circuit being broken and the flow of current being ceased.

6. Applications of Push Button Switches

The remarkable versatility of push button switches enables their usage across a wide array of applications:


Household Appliances: Push button switches are integral to many household appliances. Be it microwave ovens that warm up our meals or washing machines that launder our clothes, these switches provide a simple and reliable means of control.


Industrial Machinery: Within industrial environments, push button switches play a critical role. They are commonly used to initiate or halt machinery, often as part of larger, comprehensive control panels.


Consumer Electronics: Everyday devices such as computers, calculators, and remote controls rely heavily on push button switches for user interaction and input.

7. Advantages of Push Button Switches

Push button switches bring several benefits to the table:


Ease of Use: Their operation is undeniably intuitive, requiring nothing more than a simple press to activate or deactivate. This simplicity makes them incredibly user-friendly.


Durability: These switches are designed to endure repeated use, making them notably robust and long-lasting.


Versatility: Given the multitude of configurations they come in, push button switches display impressive versatility. This wide range of options allows them to fit seamlessly into almost any electrical application.

8. Significance in Safety Systems

Push button switches occupy a significant position in safety systems across various sectors. Emergency stop buttons, standard features in industrial setups, provide operators with the ability to instantly deactivate machinery during emergencies. Safety interlocks employ push button switches to make sure that equipment remains non-operational until certain prerequisites are fulfilled, thus enhancing safety.

9. Innovations and Future Trends

The Significance of Push Button Switches in Automation
Push button switches hold a critical position in automated systems. They act as manual interfaces, enabling the control of automated procedures.
Furthermore, they can be combined with other elements such as sensors and actuators. This amalgamation facilitates the creation of complex control frameworks, augmenting the effectiveness and functionality of automated systems.

10. Common Issues and Troubleshooting

While push button switches are generally reliable, they can encounter problems such as:

  • Contact Wear: Over time, the contacts can wear out, leading to intermittent or failed operation.
  • Sticking: Dirt or debris can cause the button to stick, preventing proper operation.
  • Electrical Failures: Issues with the internal wiring or connections can cause the switch to malfunction.

Regular maintenance and prompt troubleshooting can help address these issues and extend the life of the switch.

11.Choosing the Right Push Button Switch

Selecting the right push button switch for your application involves several factors:

  • Load Requirements: Ensure the switch can handle the electrical load of your application.
  • Environmental Conditions: Consider factors such as moisture, temperature, and dust that the switch will be exposed to.
  • Application-Specific Needs: Choose a switch that meets the specific requirements of your application, such as illumination, size, and mounting style.


Push button switches are essential components in many electrical and electronic systems. Their simplicity, reliability, and versatility make them indispensable in a wide range of applications, from household appliances to industrial machinery. Understanding the different types, how they work, and their various applications can help you make informed decisions when selecting and using push button switches.
