LED COLOR STATUS INDICATIONS

Choosing the right LED color for your 12v push button momentary switch is essential for user safety and equipment operation:

• 🔵 Blue: Often used for secondary functions or status indicators in dark environments.
• 🔴 Red: Standard for emergency stops, power-off indicators, or warning alerts.
• 🟢 Green: Indicates "Start," "System Ready," or normal operating status.
• 🟡 Yellow: Used for standby modes or caution alerts requiring operator attention.
• ⚪ White: Provides high-brightness illumination for general power status in bright areas.

INDUSTRIAL APPLICATIONS

FILN 16mm metal push button switches are widely utilized in:

• Industrial control panels & CNC machines
• Automation equipment & Robotics
• Electrical cabinets & Power distribution

• Medical devices & Laboratory equipment

INSTALLATION STEPS

1. Prepare the control panel by drilling a 16mm mounting hole.
2. Insert the momentary reset switch from the front side of the panel.
3. Secure the switch from the back using the provided metal hex nut and waterproof gasket.
4. Connect the 4-PIN terminal according to the wiring logic (refer to the guide below).

4-PIN LED Push Button Switch Wiring Guide

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 Push Button Momentary Switch?
In industrial equipment, a momentary reset switch is a type of electrical contact that only maintains its state while it is being physically actuated. Once released, it returns to its default position. It acts as the "brain" for triggering specific functions like machine startup or system resets.

Feature	Momentary (Reset)	Latching (Fixed)
Action	Springs back after press	Stays in position after press
Application	Horn, Starter, Doorbell	Main Power, Light Switch
