Key Features

1. Exceptional Protection & Durability

This 16mm metal on/off switch boasts IP65 and IK08 ratings, protecting against water, dust, and heavy impact. The silver stainless steel shell ensures it withstands harsh industrial environments without corrosion.

2. Optimized Electrical Load Capacity

Rated at 5A 250V AC/DC, this heavy-duty push button can control high-power devices directly, eliminating the need for extra relays in many circuits. The 1800V dielectric strength provides a high safety margin.

3. Superior Screw Terminal Design

The 2-pin screw terminal offers a significant advantage over solder pins: it allows for fast, secure wiring using only a screwdriver. This is ideal for field maintenance and vibration-prone applications where solder might fail.

4. High-Head Tactical Feedback

The high-head metal button provides distinct tactile feedback even when operators are wearing heavy gloves, making it perfect for CNC machines and manual automation equipment.

5. Compact Industrial Build

Despite its high current rating, the FLM16-HS-1 maintains a compact profile, allowing for dense installation on industrial control panels with limited back-space.

Applications

The 16mm metal button switch is universally used across various sectors. Every powered device requires a reliable switch to control circuit continuity. Common applications include:

• Industrial Control Panels: For machine starting and emergency signaling.
• CNC Machines: Providing manual overrides and mode selections.
• Marine Systems: Weather-resistant control for deck equipment.
• Medical Devices: Hygienic, easy-to-clean stainless steel interfaces.
• Electrical Cabinets: Reliable on-off control for power distribution.

Installation Guide

1. Drill the Panel: Create a 16mm (0.63") hole in your mounting surface.
2. Insert Switch: Place the metal push button switch through the hole from the front side.
3. Secure with Nut: From the back, thread the provided metal hex nut onto the screw body and tighten to secure the switch.
4. Wiring: Connect your wires to the 2-pin screw terminals and tighten the screws for a secure connection.

Terminal Type Comparison

Terminal Type	Pros	Installation Method
Screw Terminal	No soldering needed, vibration resistant, easy maintenance.	Screwdriver tightening
Pin Terminal	Compact, suitable for PCB or socket connection.	Soldering or Plug-in
Wired Terminal	Fastest assembly, waterproof sealing.	Direct wire splicing

3-PIN Wiring Guide (Reference)

While the FLM16-HS-1 is a 2-pin switch, here is the standard logic for 3-PIN switches often used in similar circuits:

• C (Common): Power input terminal.
• NO (Normally Open): Connects only when pressed. (Logic for FLM16-HS-1)
• NC (Normally Closed): Disconnects when pressed.

Terminals	Default	Action (Pressed)
C + NO	Device OFF	Device ON
C + NC	Device ON	Device OFF

Industry Knowledge

What is a Metal On/Off Push Button Switch?

An on/off push button switch is a fundamental mechanical component used to control the flow of electricity in a circuit. In industrial settings, these are typically momentary (the device stays on only while you hold the button) or latching (press once for ON, press again for OFF). The metal construction ensures protection against physical abuse and electrical interference.

Latching vs. Momentary: Key Differences

Feature	Momentary (This Model)	Latching
Operation	Springs back after release.	Stays in place until pressed again.
Common Use	Bells, PC Power, Starters.	Light switches, main power.
