LED COLOR INDICATOR GUIDE

Choosing the right color for your 12v led ring light switch helps in intuitive machine operation:

• RED: Danger/Stop/Emergency.
• GREEN: Ready/Start/Normal Operation.
• BLUE: Specific function/Manual mode.
• YELLOW/ORANGE: Warning/Standby.
• WHITE: General Illumination/Backlight.

APPLICATIONS

Widely used in high-power circuits and aesthetic control panels:

✔ Industrial Control Panels	✔ Marine Navigation Systems
✔ CNC Machines & Robotics	✔ Medical Imaging Equipment

INSTALLATION STEPS

1. Drill a 28mm hole in the mounting panel.
2. Insert the button from the front of the panel.
3. Secure the switch from the back using the provided metal hex nut.
4. Connect the 5 pins (C, NO, NC, LED+, LED-) according to your circuit logic.

5 Pin Push Button Switch Wiring Diagram

A 5-PIN switch offers maximum flexibility, featuring C (Common), NO (Normally Open), NC (Normally Closed), and two dedicated LED pins (+ / -). This allows for four distinct control modes.

1. Normal OFF, Sync LED (NO Connection)

Logic: Both the device and the LED are OFF by default. Pressing the button turns ON the device and the LED simultaneously.

• Application: Standard start switches where the light indicates the system is running.
• State: Static (LED Out, Device Off) → Pressed (LED On, Device On).

2. Normal ON, Sync LED (NC Connection)

Logic: Both the device and the LED are ON by default. Pressing the button turns OFF both the device and the LED.

• Application: Stop buttons or emergency cut-off switches.
• State: Static (LED On, Device On) → Pressed (LED Out, Device Stop).

3. Normal OFF, Constant LED (NO Connection)

Logic: The LED stays ON constantly as a backlight. The device only turns ON when the button is pressed.

• Application: Power switches in dark environments or access control buttons.
• State: Static (LED On, Device Off) → Pressed (LED On, Device On).

4. Normal ON, Constant LED (NC Connection)

Logic: The LED stays ON constantly. The device is ON by default and turns OFF when the button is pressed.

• Application: Monitoring systems or security alarms that require constant power indication.
• State: Static (LED On, Device On) → Pressed (LED On, Device Stop).

Mode	LED Behavior	Device (Idle)
NO Sync	Lights up when pressed	OFF
NC Sync	Turns off when pressed	ON
Constant	Always ON (Backlight)	User Choice

INDUSTRY KNOWLEDGE

What is a 12 Volt Switch Push Button?

In industrial automation, a heavy-duty metal push button serves as the primary human-machine interface (HMI). A 12V specific model is tailored for low-voltage systems found in modern control cabinets and automotive electronics. It controls the "break" or "make" of an electrical circuit safely and efficiently.

Momentary vs. Latching Function

Function	Logic	Example Use
Momentary	Springs back after release	PC Power, Doorbell, Reset
Latching	Stays in place until pressed again	Machine ON/OFF, Light Switch
