Key Features

1. Optimized Ergonomics (High-Head Design)

The high-head-led-switch design allows for a larger contact area and more precise actuation. This is especially beneficial for Western users or industrial operators wearing heavy gloves, providing a superior control experience compared to flat-head buttons.

2. Enhanced Nighttime Visibility

Featuring an illuminated ring, the stainless-steel-ring-light-switch ensures high visibility in dark or complex environments. The light guide is sharp and bright, reducing the risk of accidental operation during nighttime shifts.

3. Industrial-Grade Durability

With an IP65 waterproof rating and IK08 impact protection, this waterproof-4-pin-push-button is built to withstand harsh environments. The stainless steel shell resists corrosion and physical damage.

4. Functional Indicator Colors Meaning

• Red: Warning or Stop status.
• Green: Ready or Running status.
• Blue: Special mode or Information.
• Yellow: Caution or Standby.
• White: Power status or general lighting.

Applications

This panel-mount-metal-switch is widely used in circuits to control the power on/off state of various equipment. Its versatility makes it suitable for:

• Industrial Control Panels
• CNC Machinery
• Automation Equipment
• Electrical Cabinets
• Marine Systems
• Medical Devices

Installation Guide

1. Drilling: Create a 19mm diameter hole in the mounting panel.
2. Insertion: Place the button switch through the hole from the front of the panel.
3. Securing: Use the metal nut to fix the switch firmly from the back.
4. Wiring: Connect the 4-pin terminals to your circuit as per the wiring diagram.

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.

Industry Knowledge

What is a 12V Momentary Push Button?

A momentary push button 12V is a control switch that only remains in its active state while it is being physically pressed. Once released, it returns to its original state (Open or Closed) via a built-in spring mechanism. These are essential in modern industrial equipment for triggering signals, starting motors, or resetting systems.

Latching vs. Momentary: Which one do you need?

Function	Description	Common Use
Momentary	Self-reset: Springs back when released.	Doorbell, PC Power, Horn.
Latching	Self-lock: Stays depressed until pressed again.	Light switch, Power start.
