How Do I Choose a Push Button Switch?

1. Introduction

Choosing the right Push button switches might seem straightforward, but there’s a lot more to it than meets the eye. Whether you’re working on an industrial machine, a piece of consumer electronics, or a home automation system, the right switch can make all the difference. Let’s dive into everything you need to know to make an informed decision.

2. 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.

3. 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.

3. Applications of Push Button Switches

Industrial Applications

In industrial settings, push button switches are used to control machinery and equipment. They need to be robust, durable, and reliable to withstand harsh environments.

Consumer Electronics

From power buttons on your TV remote to game controllers, push button switches are integral to consumer electronics. They need to be responsive and durable.

Automotive Applications

Cars use push button switches for various functions, such as starting the engine or controlling the stereo. These switches must be able to endure vibrations and extreme temperatures.

Home Automation

In smart homes, push button switches control lighting, security systems, and other automated features. They should be easy to use and aesthetically pleasing.

4. Key Factors to Consider

Electrical Ratings

Understanding the electrical ratings of a switch is crucial. This includes voltage, current rating, and contact resistance. Make sure the switch can handle the electrical load of your application.

Mechanical Durability

Consider the actuation force (how hard you need to press), lifespan (how many presses it can handle), and overall build quality.

Environmental Conditions

Think about where the switch will be used. Temperature range, ingress protection (IP) rating, and resistance to factors like dust and moisture are important.

Aesthetic and Ergonomic Considerations

The design, finish, size, and shape of the switch should fit your application and be comfortable for users.

5. Understanding Electrical Ratings

  1. Voltage Rating
    The voltage rating tells you the maximum voltage the switch can handle. Ensure it matches your application’s requirements.
  2. Current Rating
    This rating indicates the maximum current the switch can carry without being damaged. Choosing a switch with the correct current rating is essential for safety and functionality.
  3. Contact Resistance
    Low contact resistance ensures minimal power loss and efficient operation. It’s a key factor in the switch’s performance.

6. Mechanical Durability

  1. Actuation Force
    This is the amount of force required to press the switch. It should be comfortable for the user but not so light that it triggers accidentally.
  2. Lifespan of the Switch
    Measured in cycles, the lifespan tells you how many times the switch can be pressed before it fails. For heavy-use applications, a high lifespan is crucial.
  3. Build Quality
    Look for switches made from durable materials that can withstand your application’s demands.

7. Aesthetic and Ergonomic Considerations

  1. Design and Finish
    The switch’s appearance should match your application’s design. Consider color, texture, and overall look.
  2. Size and Shape
    Make sure the switch is the right size and shape for its intended use. It should fit comfortably where it will be installed.
  3. User Experience
    A switch should be intuitive and easy to use. Test it to ensure it provides a good user experience.

10. Choosing the Right Manufacturer

  1. Reputation and Reviews
    Research manufacturers and read reviews to find a reputable supplier. A good manufacturer will provide reliable, high-quality switches.
  2. Warranty and Support
    Check for warranties and customer support options. This can be crucial if you encounter issues with your switch.
  3. Customization Options
    Some manufacturers offer customization options. If you need a specific design or feature, look for manufacturers who can accommodate your needs.

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.


Choosing the right push button switch involves considering various factors, from electrical ratings to environmental conditions and user experience. By understanding your specific needs and researching your options, you can find the perfect switch for your application.

Choosing Push Button Switch FAQs

1. What is the difference between a momentary and a latching push button switch?
A momentary switch is only active while pressed, while a latching switch stays in one state until pressed again.

2. How do I determine the right electrical rating for my application?
Check the voltage and current requirements of your application and choose a switch with matching or higher ratings.

3. Can push button switches be used outdoors?
Yes, but ensure they have a suitable IP rating for protection against dust and water.

4. What should I consider when choosing the design of a push button switch?
Consider the aesthetic, ergonomic factors, and how well the design fits your application.
