Key Features

• Exceptional Protection: Rated IP65 and IK08, this switch resists dust, water, and physical impact, ideal for harsh outdoor or industrial environments.
• High Electrical Load: Unlike standard 12mm switches rated at 2A, the FLM12-FJ-1 handles up to 5A 250V AC/DC, reducing the need for intermediate relays.
• Premium Material Options: Available in 304 Stainless Steel for medical and marine applications where rust resistance is critical.
• Compact Short-Body Design: Total length of only ~26.5mm makes it perfect for space-constrained control panels and handheld devices.
• Efficient 2-Pin Terminal: Standard 2.8mm pins support both soldering and quick-connect wire harnesses for high-efficiency assembly.

Applications

Industrial control panels CNC machines Automation equipment Electrical cabinets Marine systems Medical devices

Installation Guide

1. Panel Preparation: Drill a precise 12mm diameter hole in your mounting surface.
2. Insert Switch: Place the button actuator through the hole from the front side of the panel.
3. Secure Nut: Slide the metal hex nut from the back and tighten it against the panel thread.
4. Wiring: Connect your circuit to the two pin terminals using either soldering or 2.8mm connectors.

Wiring Guide (Normally Open Logic)

The 2-pin momentary switch operates on a simple Normally Open (NO) logic. The circuit completes only when the button is held down.

Wiring Logic: Power (+) connects to Pin 1; Device (+) connects to Pin 2.

• Idle State: Circuit Disconnected (Device OFF).
• Pressed State: Circuit Connected (Device ON).

Industry Knowledge

1. What is a 12mm metal push button switch?

A 12mm metal push button switch is a compact electrical component used to control the flow of current in a circuit. In industrial settings, these switches are favored for their durability and "vandal-proof" nature. They are panel-mounted and provide a tactile response to the user, ensuring clear operation feedback. Being "momentary" means they only maintain their state while actively being pressed.

2. What is the difference between latching and momentary?

Feature	Momentary (This Model)	Latching (Push-Lock)
Action	Springs back after release	Stays depressed/locked
State Reset	Automatic	Requires second press
Common Use	Horns, Doorbells, PC Start	Light switches, Power Mains
