LED SPECIFICATIONS & COLOR MEANINGS

The ring led button provides visual status indicators for different machine states:

• 🔴 Red: Emergency stop, danger, or system failure.
• 🟢 Green: Normal operation, system ready, or power on.
• 🔵 Blue: Specific instruction status or remote control indicator.
• 🟡 Yellow: Warning, standby mode, or caution.
• ⚪ White: General circuit status or illumination.

KEY FEATURES

1. Superior IP67 Protection: This ip67 waterproof momentary switch is fully sealed, allowing for stable use in damp, dusty, or outdoor industrial conditions.

2. Ultra-Thin Design: The compact structure of this ultra-thin metal push button makes it ideal for panels with limited rear-side clearance.

3. Long Service Life: With a mechanical life of 100,000 cycles, it outperforms standard commercial switches, reducing maintenance costs.

4. High-Quality Silver Contacts: Ensures minimal contact resistance (≤ 50mΩ) and excellent conductivity for precise signal triggering.

5. Flexible Wiring: The 19mm momentary switch with wire socket design and 15cm tail leads significantly speed up installation compared to traditional pin terminals.

• Security systems and access control

INSTALLATION STEPS

1. Prepare the mounting panel and drill a 19mm diameter hole.
2. Insert the button switch from the top (front) side of the panel.
3. Place the rubber washer on the back side of the panel.
4. Tighten the metal hexagonal nut onto the threaded body to fix the switch firmly (Recommended torque: 5-10N.m).
5. Plug the 15cm wire socket onto the button pins and perform standard wiring to your circuit.

4 Pin Push Button Switch Wiring Diagram

A 4-PIN switch consists of two parts: Switch Contacts (to control the device) and LED Terminals (marked with + and -). Below are two ways to wire the LED indicator.

• Horizontal Pins: The switch mechanism (Power In / Load Out).
• Vertical Pins (+ / -): The LED indicator light terminals.

Method 1: LED Synchronized with Device (On when Active)

Logic: The button light only turns ON when the device is running. It serves as a "Status Indicator."

• Wiring: Connect LED (+) to the Output side of the switch. LED (-) to Power Negative.
• Applications: Power start buttons, car fog lights, industrial machinery.
• Benefit: Saves power; provides visual feedback that the system is active.

Method 2: LED Always ON (Backlight Mode)

Logic: The button light stays ON constantly as long as there is power, regardless of the button position.

• Wiring: Connect LED (+) directly to the Power Positive. LED (-) to Power Negative.
• Applications: Dark environments, hallway switches, standby power indicators.
• Benefit: Allows you to find the switch easily in total darkness.
