Introduction

In industrial control systems, the push button switch remains one of the most fundamental yet critical components. Among all options, metal push button switches with LED indicators stand out for their durability, clarity, and weather resistance.

Today, we analyze a typical 12×12.2mm metal push button switch, covering its electrical ratings, mechanical characteristics, waterproof performance, and practical wiring – all backed by real technical data.

If you’re a control panel builder, equipment OEM, or procurement engineer, this guide will help you select and use this switch correctly.

1. Key Technical Specifications

Mounting & Mechanical Data

✅ These values ensure long mechanical life and stable performance even in harsh environments.

Electrical Ratings

💡 The Ith 3A rating means the switch can handle higher inrush currents for short durations – ideal for small motors or solenoids.

LED & Illumination

Customizable LED voltage allows integration with 6V, 12V, 24V, or even 220V systems.

2. Waterproof & Environmental Performance

• Standard waterproof rating: IP65 at the button face

• Optional: IP67 (customizable)

🔧 For outdoor equipment, food processing machinery, or marine applications, IP67 customization is strongly recommended.

3. Switch Combinations & Working Principle

This switch is available in multiple contact configurations:

• 1NO (1 normally open)

• 1NC (1 normally closed)

• 1NO + 1NC (common for two‑circuit control)

Working States (Momentary Action)

This momentary action is ideal for start/stop controls, horn buttons, or jog operations.

4. Mechanical Design & Installation

Dimensions (excerpt)

• Mounting thread: M12 × 0.75

• Panel cutout: 12 × 12.2 mm (non‑circular, anti‑rotation design)

⚠️ Always verify the cutout shape – this is not a standard round 12mm hole. A 12×12.2mm rectangular/keyed hole is required.

Terminal Style

• PIN pin style (solder or quick‑connect terminals)

• Easy to integrate into PCB or wire harness

5. How to Wire This Metal Push Button Switch (With LED)

Pinout (typical for illuminated 5‑pin version)

Basic Wiring Diagram

Non‑illuminated (NO mode):
Live → COM → NO → Load → Neutral

Illuminated (light when pressed):

• Live → COM and jump to LED+

• LED– → Neutral

• NO → Load

🔌 Always match LED voltage with your control circuit (e.g., 24V LED requires 24V supply).

6. Typical Industrial Applications

Thanks to its metal housing, IP65 rating, and customizable LED, this switch is widely used in:

• Industrial control panels (start/stop stations)

• CNC machinery (cycle start, emergency stop)

• Food & beverage equipment (washdown‑ready with IP67 option)

• Marine electronics (resistant to humidity and salt spray)

• Medical devices (easy‑to‑clean metal surface)

• Public kiosks & vending machines (vandal‑resistant)

7. Sourcing & Customization Notes for B‑Buyers

When requesting a quote or sample, please provide the following information to ensure correct configuration:

1. LED color (red / green / yellow / blue / white)

2. LED voltage (e.g., 12V DC, 24V DC, 220V AC)

3. Contact configuration (1NO / 1NC / 1NO+1NC)

4. Waterproof rating (IP65 or IP67)

5. Housing material (SUS304 / brass nickel‑plated / anodized aluminum)

6. Terminal type (pin / solder / wire lead)

📦 MOQ typically starts from 100–500 pcs for custom colors or IP67 upgrades. Stock versions with red/green LED and IP65 are usually available for sample orders.

Conclusion

The 12×12.2mm metal push button switch with LED combines mechanical ruggedness, electrical reliability, and visual feedback in a compact footprint. Whether you need IP65 for indoor industrial panels or IP67 for outdoor/washdown environments, this switch family offers a cost‑effective solution.
