Key Features of the FLM19-FW-3-E
1. Ultra-Short Body for Space-Constrained Panels
The compact body design is intended for equipment with restricted rear-panel clearance. It can help simplify integration into compact control panels, instruments, and machinery where available installation depth is limited. Check the dimensional drawing before finalizing the panel layout.
2. IP67 Front Protection and IK08 Impact Rating
The supplied specifications list IP67 front protection and IK08 impact resistance. These ratings can help engineers evaluate suitability for demanding environments. Actual protection depends on correct mounting, sealing, and the applicable test conditions.
3. Metal Construction and Multiple Finish Options
Material options listed for this series include 304 stainless steel, H59 brass, and 6063 aluminum alloy. The selected material and finish should be confirmed for the required corrosion resistance, appearance, and installation environment.
4. Illuminated LED Ring for Status Identification
The LED ring provides visual feedback on a control panel. Common industrial conventions include red for warnings or stop conditions, green for normal operation, yellow for caution, blue for selected functions, and white for general indication. These meanings are application-dependent and should follow the equipment's control logic and applicable standards.
5. Pre-Wired 4PIN Connection
The supplied 4PIN configuration combines the switch contact circuit and LED terminals. Pre-wired connections can simplify assembly, but wire assignments, polarity, voltage, and connector details must be verified before installation.

Typical Application Areas for Push Button Switches19mm Push Button Switch Installation Guide
Before installation, disconnect the power supply and confirm that the mounting hole and available rear-panel clearance match the selected model.
- Prepare a mounting hole with a diameter of 19mm, subject to the product drawing and specified tolerances.
- Remove the fastening nut from the rear of the switch.
- Insert the switch head through the mounting hole from the front of the panel.
- Install and tighten the nut from the rear according to the manufacturer's recommended torque.
- Connect the switch contacts and LED terminals according to the wiring diagram.
- Inspect the installation and test the circuit before returning the equipment to service.
4PIN Push Button Switch Wiring Configuration
The 4PIN configuration described in the supplied product information contains two switch contacts and two LED terminals. Identify each terminal from the actual model's wiring diagram rather than relying on physical orientation alone.
Switch contacts: Used to control the connected circuit.
LED terminals (+ / -): Used to power the illuminated ring. Observe the specified polarity and rated voltage.
Method 1: LED Synchronized with the Controlled Device
In a status-indicator configuration, the LED is powered by a suitable signal or supply that becomes active when the controlled device is running. The exact connection depends on the circuit and the desired indication logic.
- Purpose: Indicate that the equipment or selected function is active.
- Typical applications: Start controls, machinery interfaces, and auxiliary controls.
- Important: Do not assume that the LED can be connected directly to the switch output without checking voltage, polarity, and circuit design.
Method 2: LED Continuously Illuminated While Powered
In a backlight configuration, the LED is connected to a suitable power source independently of the switched load, so the ring can remain illuminated while the indicator supply is present.
- Purpose: Make the button easier to locate or identify.
- Typical applications: Low-light environments and illuminated control panels.
- Important: Use the specified LED supply voltage and a suitable circuit arrangement.
| LED Mode | LED at Rest | LED When Pressed |
|---|---|---|
| Device Status Indication | Depends on the status signal | Depends on the status signal |
| Continuous Backlighting | ON when the LED supply is present | ON when the LED supply is present |
These are functional wiring concepts, not a substitute for the model-specific schematic. The LED does not necessarily turn on simply because the mechanical button is pressed.
Push Button Switch Selection Guide
What Is an Ultra-Short Push Button Switch?
An ultra-short push button switch is an electromechanical control component designed to reduce the space occupied behind a mounting panel. It can be useful in compact human-machine interfaces (HMIs), instrumentation, and industrial control assemblies where rear clearance is limited.
