Button Switch Drawing
Product Overview
The FILN 19mm key push button switch (FLM19-KJ-1) is a high-performance industrial control component designed for security and precision. Built with a 304 stainless steel shell, this 3-pin key operated push button provides a robust alternative to standard switches by requiring a physical key for operation. Unlike traditional momentary or latching buttons, this 2-position key selector switch ensures authorized access for critical systems. Certified with ISO9001, CE, VDE, RoHS, SGS, and UL, it offers an IP65 waterproof rating, making it ideal for industrial-panel-mount-key-switch applications in automation, marine systems, and electrical cabinets. As a leading factory, FILN provides high-security metal key switch solutions with full customization support.

Key Features
- Enhanced Security: Unlike standard buttons, the stainless-steel-rotary-key-switch requires a key, preventing unauthorized tampering.
- Extreme Durability: With IP65 & IK08 ratings, it withstands moisture, dust, and physical impact.
- High Load Capacity: Supports up to 5A 250V, allowing direct control of heavy equipment without extra relays.
- Premium Materials: The silver contact (AgCdO12) ensures low resistance and long-term conductivity.
- Compact Design: A short-body structure (approx. 26.5mm) makes it perfect for metal-key-switch-for-control-panel setups with limited space.
Applications
This waterproof-key-actuated-switch-ip65 is widely used in:
- Industrial control panels and CNC machines.
- Security systems and emergency power cut-offs.
- Medical equipment and food processing machinery.
- Automotive and marine dashboard controls.
Installation Guide
- Drill a 19mm diameter hole in your control panel.
- Place the silicone waterproof ring onto the switch body.
- Insert the switch through the panel hole from the front.
- Secure the switch by tightening the M19 metal nut from the back.
- Connect the 3-pin terminals according to your circuit requirements.
3-PIN Key Switch Wiring Methods
A 3-PIN switch consists of a Common (C), Normally Open (NO), and Normally Closed (NC) terminal. Use these connections to control the circuit state via the key.
- C (Common): Power input terminal.
- NO (Normally Open): Connects only when the key is turned to the ON position.
- NC (Normally Closed): Disconnects when the key is turned.
Method 1: Normally Open (NO) Connection
Logic: Device stays OFF by default and turns ON only when the key is rotated.
- Wiring: Power (+) to C, Device (+) to NO.
- Applications: Machinery start, secure ignition.
Method 2: Normally Closed (NC) Connection
Logic: Device stays ON by default and turns OFF when the key is rotated.
- Wiring: Power (+) to C, Device (+) to NC.
- Applications: Emergency stops, security lockout.
Industry Knowledge
1. What is a 19mm Key Push Button Switch?
A 19mm-key-lock-switch-wiring setup is used for high-security environments. It functions as a rotary selector but requires a physical key. This is essential for industrial-panel-mount-key-switch needs where only authorized personnel should toggle power to hazardous or sensitive machinery.
2. Comparison: Key Switch vs. Regular Push Button
| Feature | Standard Push Button | FILN Key Switch |
|---|---|---|
| Security | Low (Anyone can press) | High (Requires physical key) |
| Functions | Momentary/Latching | 2-Position (ON/OFF) |
| Installation | Threaded Mount | Threaded Mount (M19) |
| Durability | Standard | Enhanced Mechanical Stability |
