1. Superior Protection & Durability: Rated IP65 and IK08, this switch is waterproof, dustproof, and resistant to physical impact, making it ideal for outdoor and harsh industrial environments.
2. High Electrical Load Capacity: Supports up to 5A 250V AC/DC, allowing it to control higher power devices directly without an intermediate relay.
3. Premium Silver Contacts: The use of AgCdO12 silver contacts reduces contact resistance (< 50mΩ) and enhances electrical life.
4. Compact Short-body Design: With a mounting depth of only 26.5mm, it fits perfectly in shallow control boxes and handheld equipment.

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.
Logic: The button light only turns ON when the device is running. It serves as a "Status Indicator."
Figure 1: LED turns ON only when button is pressed
Logic: The button light stays ON constantly as long as there is power, regardless of the button position.
Figure 2: LED stays ON constantly (Backlight)
| Mode | LED Status (Idle) | LED Status (Pressed) |
|---|---|---|
| Sync (Status) | OFF | ON |
| Always ON (Backlight) | ON | ON |
It is a compact electrical control component where the circuit is closed only while the button is physically held down. Once released, it springs back to its original state. The integrated LED provides status indication, making it essential for automation and user interface panels.
| Feature | Momentary (This Model) | Latching |
|---|---|---|
| Action | Springs back instantly | Stays in place (On/Off) |
| Common Use | Horns, Reset, Starters | Main Power, Light Switches |
