Momentary push button switch are everywhere around us, yet many people don’t realize how versatile and important these small components are. Whether it’s the doorbell you press or buttons on industrial control panels, momentary push button switches play a crucial role in temporarily activating circuits. If you’ve ever wondered about the different types of momentary push button switches, how they work, or which type suits your application best, you’re in the right place.
In this article, we’ll explore the key types and classifications of momentary push button switches, guiding you through their working principles, structural varieties, common applications, and how to choose the right switch for your project or product.
Let’s dive in and uncover what makes these switches tick and how you can leverage their types and features for your industrial, commercial, or consumer needs.
What is a Momentary Push Button Switch?
A YJ-GQ16A momentary push button switch is a type of electrical switch that only stays active as long as the button is being pressed. Once you release it, the switch returns to its original position and cuts off the electrical circuit immediately. This temporary action makes momentary switches ideal for applications where brief control signals are needed—think of a doorbell or a keyboard button.
| Feature | Description |
|---|---|
| Action duration | Only while pressed |
| Default state | Open or Closed, depends on switch type |
| Circuit change | Temporary connection or disconnection |
Momentary switches differ from maintained (or latching) switches, which stay in the new state even after being released. Common terms you might hear related to momentary switches are “normally open (NO)” and “normally closed (NC)”. A normally open momentary switch only closes the circuit while pressed, whereas a normally closed one breaks the circuit when pressed.

Types of Momentary Push Button Switch
Momentary push button switch YJ-GQ16A come in various types based on their structure, functionality, and application environment. Understanding these can help you pick the perfect one that balances durability, tactile feedback, appearance, and technical requirements.
1️⃣Classification by Electrical State
| Type | Description | Use Case Example |
|---|---|---|
| Normally Open (NO) | Circuit completes only when pressed | Doorbells, buzzers |
| Normally Closed (NC) | Circuit breaks only when pressed | Emergency stop buttons |
| Double Throw (DT) | Switch toggles between two circuits | Equipment mode selection |
2️⃣Classification by Structure and Function
| Type | Features | Typical Applications |
|---|---|---|
| Tactile Momentary Switch | Compact, compact click feedback | Consumer electronics, keyboards |
| Illuminated Switch | Built-in LED for status indication | Industrial control panels, dashboards |
| Waterproof Momentary Switch | Sealed against water/dust ingress | Outdoor equipment, marine electronics |
| Micro Switch | Sensitive, small size | Appliances, automotive door switches |
| Foot Switch | Operated by foot, frees hands | Medical equipment, musical pedal controls |
| Capacitive Touch Switch | Detects touch without physical press | Smartphones, tablets, modern appliances |
| Piezo Switch | Uses piezoelectric effect, rugged | Military, harsh environments |
| Membrane Switch | Flat, flexible with layered design | Medical devices, appliances |
| Rotary Momentary Switch | Activated by rotation, resets | Instrumentation, communication devices |
| Slide Momentary Switch | Activated by sliding, returns | Portable devices, toys |
Interesting fact: Did you know illuminated momentary switches can help operators quickly verify if a function is active, especially in dimly lit control rooms?
3️⃣Classification by Mounting Style
| Mounting Type | Description | Common Usage Example |
|---|---|---|
| Panel Mount | Installed on control panels | Industrial machines |
| PCB Mount | Directly mounted on circuit boards | Consumer electronics |
To make it easy: If your project involves integration into a control panel, a panel mount switch is usually best. For compact device boards, PCB mount is preferred.

Applications of Momentary Push Button Switches
Momentary push button switches are versatile and widely used across many sectors including:
| Industry/Application | Typical Use Cases |
|---|---|
| Industrial Automation | Machine start/stop controls |
| Consumer Electronics | Keyboards, remote controls |
| Automotive | Ignition buttons, door sensors |
| Medical Equipment | Foot switches for hands-free control |
| Security Systems | Alarm triggers |
| Household Appliances | Microwave start buttons, doorbells |
This diversity is due to the large range of momentary switch types available, each fine-tuned to specific needs like water resistance or tactile feedback.
Choosing the Right Momentary Push Button Switch
Selecting the perfect switch requires balancing several factors:
| Factor | Consideration | Impact on Choice |
|---|---|---|
| Electrical Ratings | Voltage & current capacity | Ensures safe and reliable operation |
| Environmental | Waterproofing (IP rating), temperature range | Longevity and durability |
| Mechanical Specs | Size, mounting type, actuation force | User comfort & installation ease |
| Feedback Type | Tactile click, smooth, illuminated | User experience |
| Actuator Material | Metal, plastic, rubber | Aesthetics & robustness |
For industrial metal push button switches, high durability and water/dust resistance are often critical. Metal buttons also offer a premium feel and better longevity.
Tip: Always check the datasheets for momentary switch electrical specifications to make sure it fits your circuit.
Momentary push button switch may seem like simple devices, but their types and applications are vast and important. Understanding the distinctions—like normally open vs normally closed, or choosing between tactile, illuminated, or waterproof switches—helps you find the ideal product for any electrical project or machine.
Whether you’re building industrial control panels, consumer electronics, or custom equipment, selecting the right momentary push button switch ensures reliable, precise control with the right feel and durability. Remember, the best switch for you depends on your specific needs — electrical ratings, environmental conditions, user experience, and installation method all matter.
