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

Frequently Asked Questions

1. Can the FLM19 switch handle 220V?
Yes, we offer specific versions for 110-220V AC with integrated resistors for the LED.

2. What is the difference between latching and momentary?
Latching stays in place when pressed (on/off); momentary springs back immediately (pulse signal).

3. Is the LED ring replaceable?
The LED is integrated for IP65 protection and long life, thus not separately replaceable.

4. Is there a black metal version?
Yes, we offer zinc-aluminum alloy with a durable black anodized finish.

5. What wire size fits the 5-pin terminal?
We recommend 22AWG to 18AWG wires or using our custom socket connector.

6. Can you customize the LED to be bi-color?
Yes, we can produce Red/Green or other bi-color combinations in a 6-pin configuration.

7. How long is the delivery time?
Standard orders usually ship within 3-7 working days.

8. Is the stainless steel rust-proof?
Yes, we use high-quality 304 stainless steel suitable for marine and outdoor use.

9. Does it come with the rubber gasket?
Every switch includes a high-grade silicone waterproof gasket.
