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.

View Push Button Switch Collection Applications of 19mm Metal Push Button Switches A 19mm momentary illuminated push button switch can be considered for equipment that needs a compact manual control and visual status indication. Application suitability depends on the circuit rating, environmental conditions, and installation requirements. Industrial control panels and automation equipment CNC cutting and machining equipment Electrical control and distribution cabinets Marine and yacht control consoles Medical and laboratory instruments, where applicable ratings are verified Access control systems and security equipment Typical Application Areas for Push Button Switches 19mm 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. Panel Mounting Steps 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. Figure 1. LED synchronized with the device status 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. Figure 2. LED continuously illuminated while powered 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. Momentary vs. Latching Push Button Switches Choose the switch action according to the required control behavior. The FLM19-FW-3-E described here is a momentary, self-reset model. Feature Momentary Latching Action Contacts change state while pressed and return when released. Maintains the selected state after release until operated again or reset. Typical Uses Start commands, signal inputs, horns and triggers. Maintained control functions and selected on/off operations. Pin Terminals vs. Screw Terminals vs. Pre-Wired Connections Connection Type Characteristics Typical Application Pin Terminals Compact connections for compatible soldering or connectors. Electronic assemblies and space-limited installations. Screw Terminals Field wiring using compatible conductors and tools. Control cabinets and electrical equipment. Pre-Wired Factory-attached wires can simplify assembly. Production lines and equipment with defined harness requirements.
