Choosing the right momentary push button switch can feel like finding a needle in a haystack. Whether you’re controlling industrial machinery or designing consumer electronics, the correct switch ensures reliability and user satisfaction.
These YJ-GQ22B switches play a crucial role by providing precise control — they complete a circuit only while being pressed, making them ideal for many applications. In this guide, we’ll explore everything you need to know about momentary push button switches, helping you select the perfect one for your needs.
What Is a Momentary Push Button Switch?
A momentary push button switch is a type of switch that only remains active while you press it. Once released, it returns to its default state, breaking the circuit immediately. This on-demand action makes them suitable for functions like doorbells, reset buttons, or industrial controls.
| Feature | Description |
|---|---|
| Operation | Circuit closes only when pressed |
| Return type | Spring returns switch to original state |
| Types | Normally Open (NO) and Normally Closed (NC) |
For example, with a Normally Open switch, pressing the button closes the circuit, allowing current to flow. Release it, and the circuit opens again. This mechanism ensures safety and prevents unintended continuous operation.
Main Types of Momentary Push Button Switches
Momentary switches are diverse, and knowing different types helps you pick the right one:
- Structure & Shape
- Flat Button
- Raised Button
- Mushroom Head (large emergency stop style)
- Contact Arrangement
- Single Pole Single Throw (SPST)
- Double Pole Double Throw (DPDT), etc.
- Additional Features
- Illuminated (LED backlight for status indication)
- Waterproof (IP65, IP67 ratings)
- Anti-vandal rugged designs for harsh environments
| Type | Typical Use | IP Rating | Durability |
|---|---|---|---|
| Flat Button | Control panels | IP65 | Up to 100,000 cycles |
| Mushroom Head | Emergency stops | IP67 | Over 200,000 cycles |
| Illuminated | Status feedback | IP54 or higher | Varies |
Considering factors like waterproof rating is vital if your switch faces moisture or dust.
How to Choose the Perfect Momentary Push Button Switch?
Here are key points to consider before finalizing your choice:
1. Application Environment
- Indoor or Outdoor: Outdoor usage demands higher IP ratings (e.g., IP65+)
- Temperature Ranges: Industrial settings might require switches rated for -20°C to +55°C or higher
- Mechanical Stress: High vibration or dusty environments require rugged designs
2. Electrical Specifications
Choosing a switch with the correct voltage and current rating prevents failures.
| Parameter | Requirement |
|---|---|
| Rated Voltage | Match or exceed your system voltage (e.g., 12V, 24V, 125VAC) |
| Rated Current | Ensure it supports your load (e.g., 2A, 5A) |
| Contact Resistance | Lower resistance means better conductivity (e.g., 10mΩ max) |
3. Mounting and Size
- Measure the panel or device mounting hole precisely (common sizes: 12mm, 16mm, 19mm, 22mm)
- Choose between panel mount or PCB mount
- Consider ergonomics: larger buttons might be easier to press under stress
4. Lifespan and Durability
Check both mechanical lifespan (e.g., 200,000 cycles) and electrical lifespan (at full load) to ensure longevity.
5. Additional Features
- Illumination: Useful for status indication, especially in low light
- Anti-vandal: Prevents damage and tampering in public environments
- Feedback: Audible clicks or tactile sensation improve user interaction

Comparing Momentary vs. Other Switch Types
| Feature | Momentary Switch | Latching (Maintained) Switch |
|---|---|---|
| Action | Circuit only active when pressed | Circuit stays on until pressed again |
| Use Case | Elevator buttons, reset buttons | Light switches, power toggles |
| Safety | Safer for emergency stops | Less suitable for emergency use |
Knowing these differences helps avoid costly mistakes in your project.
Momentary Push Button Switch in Industrial Automation
Momentary switches are everywhere in industrial automation:
- Start/Stop machines: Press to control without continuous power consumption
- Emergency stop: Big mushroom head buttons quickly break circuits to stop machinery
- Control panels: Operators get tactile, immediate feedback on commands
| Industry | Typical Switch Type | Features Needed |
|---|---|---|
| Manufacturing | IP65 rated metal switches | Robust, anti-vandal, waterproof |
| Automotive | Illuminated push buttons | Visual feedback, compact size |
| Consumer Electronics | Small tactile momentary switches | Low force, compact |
Choosing the right switch ensures uptime and operator safety.
Tips for Buying and Customizing Momentary Push Button Switches
When sourcing a reliable switch:
- Request samples to test quality firsthand
- Know your specific needs: size, colors, force needed
- Opt for suppliers offering customization: branding, engraving, LED color
Many manufacturers offer modular switch units allowing combinations to fulfill complex control needs. Investing in quality upfront pays off in maintenance savings and user satisfaction.
Selecting the right metal push button switch isn’t just about picking a button. It’s about understanding your environment, electrical needs, and user experience. From waterproof industrial models to compact illuminated switches for electronics, the perfect choice boosts reliability and safety. Remember that good communication with your supplier will save headaches as your product reaches the market. Ready to find your ideal switch?
