Key Product Features
1. Superior Protection Rating and Heavy-Duty Durability
Featuring an IP67 waterproof rating and IK08 anti-vandal resistance, this high-head metal button switch far outclasses low-tier IP40 switches. Its rugged design thrives under harsh outdoor conditions, high-humidity manufacturing plants, or shock-prone agricultural machinery.
2. Optimized High-Current Load Capacity
While most compact 19mm panel switches max out at 2A or 3A, the FLM19-HW-2-E delivers a full 5A 250V AC / 5A 36V DC rating. This allows direct switching of heavy power loads without needing external intermediate relays, saving control cabinet space and wiring complexity.
3. Hybrid Material Design & Silver Contacts
By combining a silver-finish stainless steel high head button face with a high-strength PA66+GF20% flame-retardant body, it minimizes component weight while keeping premium aesthetics. Internal AgCdO12 silver contacts drastically reduce contact resistance (≤50mΩ) and eliminate arcing risks.
4. High Head Ring-Illuminated Visual Advantage
The elevated high-round head profile provides clear tactile feedback for glove-wearing machine operators, while the integrated ring LED illumination provides vivid status feedback across a universal 3V-220V working voltage range.
5. Pre-Wired Harness & Snap-In Mounting Efficiency
Eliminate tedious manual soldering on production lines. Equipped with a 4-pin pre-wired harness (20cm PTFE Teflon wires) and dual side snap-in plastic clips, installers can mount and wire panels in seconds.
Industrial & Commercial Applications
The industrial panel mount push button switch is widely deployed across diverse electrical circuits where reliable circuit switching and visual status signaling are required:
- Industrial Control Panels: Main operational start/stop controls for factory automation systems.
- CNC Machines & Lathes: Spindle controls, coolant pump toggles, and manual override switches.
- Automation Equipment: Conveyor belt controllers, sorting machinery, and robotic cell power switches.
- Electrical Distribution Cabinets: Power supply bypass switches and status indicator toggles.
- Marine Systems: Waterproof dashboard controls for commercial vessels and off-shore equipment.
- Medical Devices: Sterilizer power switches and laboratory instrument control panels.
Installation Guide
- Cut Panel Opening: Drill or punch a precise 19mm (0.75 in) round mounting hole into your instrument panel.
- Insert Switch Body: Push the switch forward through the front face of the panel until the high head bezel sits flush against the outer panel surface.
- Secure Snap Clips: Ensure the lateral plastic retention snap-clips on the switch body expand behind the panel face to firmly lock the unit into position.
- Connect Pre-Wired Leads: Take the rear 4-pin pre-wired harness (20cm) and connect it to your 12V DC or AC system according to your selected LED control mode.
12v LED Push Button Switch Wiring Guide
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[cite: 2].
- Horizontal Pins: The switch mechanism (Power In / Load Out)[cite: 2].
- Vertical Pins (+ / -): The LED indicator light terminals[cite: 2].
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."[cite: 2]
- Wiring: Connect LED (+) to the Output side of the switch. LED (-) to Power Negative[cite: 2].
- Applications: Power start buttons, car fog lights, industrial machinery[cite: 2].
- Benefit: Saves power; provides visual feedback that the system is active[cite: 2].
Figure 1: LED turns ON only when button is pressed[cite: 2]
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[cite: 2].
- Wiring: Connect LED (+) directly to the Power Positive. LED (-) to Power Negative[cite: 2].
- Applications: Dark environments, hallway switches, standby power indicators[cite: 2].
- Benefit: Allows you to find the switch easily in total darkness[cite: 2].
Figure 2: LED stays ON constantly (Backlight)[cite: 2]
| Mode | LED Status (Idle) | LED Status (Pressed) |
|---|---|---|
| Sync (Status) | OFF | ON |
| Always ON (Backlight) | ON | ON |
Industry Knowledge
1. What is a 19mm Push Button On Off Switch 12V and Its Industrial Role?
A push button on off switch 12v is a compact panel-mounted electromechanical control device engineered to manually open or close an electrical circuit. In modern industrial automation, it serves as the primary physical human-machine interface (HMI). Every powered machine requires physical switches to control circuit power state, isolate safety systems, or initiate functional sub-routines. The 19mm cut-out dimension represents an industry standard balance between minimal panel space utilization and effortless operator accessibility.
2. What is the Difference Between Latching and Momentary Push Button Switches?
Understanding the physical contact behavior is vital when specifying switches for industrial machinery circuits:
| Feature Parameter | Latching Switch (Self-Locking) | Momentary Switch (Self-Resetting) |
|---|---|---|
| Operating Principle | Pressing the button changes contact state; it stays locked in position until pressed a second time. | Pressing the button changes contact state; releasing it causes internal spring to return it to default state immediately. |
| Common Terminology | Maintained, Push-On / Push-Off, Self-Locking | Auto-Reset, Spring Return, Pulse Trigger |
| Typical Applications | Main system power switches, work lighting toggles, continuous pump runs. | Engine starter buttons, horn controls, door chimes, jog controls on CNC machines. |
3. Wiring Connection Types: Pre-Wired vs Pin Terminals vs Terminal Connectors
| Connection Type | Key Advantages | Best Suited Application |
|---|---|---|
| Direct Pre-Wired (FLM19 Series) | Zero soldering needed; factory IP67 sealed rear base; fastest batch assembly. | High-vibration equipment, outdoor panels, rapid assembly OEM lines. |
| Pin Terminals (2.8x0.5mm) | Allows direct wire soldering or quick-connect female spade crimps. | Custom prototype panels and low-volume field technician installs. |
| Quick-Plug Socket Connector | Enables 1-second maintenance swap out without rewiring terminal leads. | Modular industrial cabinets requiring frequent service routines. |
