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

• 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.

Conclusion

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.

5. How do I maintain and clean my push button switch?
Regularly inspect and clean the switch, following the manufacturer’s guidelines. Replace any worn-out parts to maintain performance.
