- Secure the switch from behind using the provided metal hex nut.
- Connect the pre-wired 4-pin leads to your circuit following 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.
Figure 1: LED turns ON only when button is pressed
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.

| Mode | LED Status (Idle) | LED Status (Pressed) |
|---|---|---|
| Sync (Status) | OFF | ON |
| Always ON (Backlight) | ON | ON |
Industry Knowledge
What is a Latching Push Button Switch?
A latching push button switch (self-locking) stays in the "ON" position after being pressed. It requires a second press to return to the "OFF" position. This is ideal for power switches on machinery. Conversely, a momentary switch only stays "ON" as long as your finger is pressing it (like a doorbell).
| Feature | Latching (Self-Lock) | Momentary (Self-Reset) |
|---|---|---|
| Action | Stays Pressed | Springs Back |
| Best For | Main Power, Lights | Horns, Ignitions, Starters |
