19mm Metal Stop Button

A 19mm metal emergency stop button (commonly known as "e-stop button") is a safety-critical device designed to immediately halt machinery or equipment in emergency situations. With a diameter of 19mm, it features a metal construction for durability and is typically mounted on control panels or equipment surfaces for quick access.

The 19mm Metal Emergency Stop Button, a crucial safety device, is designed to halt machinery instantly in critical situations. With a diameter of 19mm, it features a sturdy metal casing, usually made of stainless steel or zinc alloy, providing excellent corrosion resistance, wear resistance, and mechanical strength to endure harsh industrial environments.

Typically mushroom - shaped and colored bright red for high visibility, it can be easily and quickly pressed by operators. It is panel - mounted through a 19mm hole, secured with a threaded ring or nut, ensuring a stable installation. In normal operation, its normally closed contacts keep the control circuit connected, allowing equipment to run. But when an emergency occurs, pressing the button breaks these contacts, immediately cutting off power to motors and other components, bringing the equipment to a halt. A manual reset, often by twisting the button, is needed to restore the circuit for subsequent operation.

Rated commonly at 250V and 5A, with high - performance electrical properties like low contact resistance and high insulation resistance, it guarantees reliable performance. Widely applied in industrial production lines, transportation systems, and public facilities, this button plays a vital role in safeguarding personnel and equipment from potential hazards.

Key Features

• Design & Appearance

• Mushroom-head shape for easy and intuitive pressing, with a bright red color for high visibility.

• Metal housing (often stainless steel or zinc alloy) for corrosion resistance, wearability, and mechanical strength.

• Installation & Protection

• Panel-mounted design with a threaded ring or nut, fitting into a 19mm diameter hole for secure attachment.

• High protection ratings (e.g., IP65/IP67) to resist dust, water, and oil in harsh environments.

• Operation

• Normally closed (NC) contact in the default state, breaking the control circuit when pressed to stop equipment instantly.

• Manual reset required (typically by twisting the button head) to restore normal operation.

Working Principle

1. Circuit Connection: Wired in series with the equipment’s control circuit. The NC contact remains closed during normal operation, allowing the circuit to function.

2. Emergency Activation: Pressing the button opens the NC contact, cutting off power to motors, contactors, or other electrical components, halting the equipment immediately.

3. Reset Mechanism: After the emergency is resolved, the button is manually reset to reconnect the circuit and enable restarting.

Applications

• Industrial Settings: Used in production lines, machine tools, cranes, and elevators to stop equipment during malfunctions or safety threats.

• Transportation: Installed in rail vehicles (e.g., subways, light rails) and special-purpose vehicles for emergency braking.

• Public Facilities: Found on escalators, amusement rides, and machinery in malls, theaters, or stadiums to protect public safety.

The 19mm metal e-stop button is a critical component of industrial safety systems, minimizing risks of accidents, injuries, or equipment damage by enabling immediate shutdown. Its robust metal construction ensures reliability in demanding environments, making it a standard safety feature across various industrie
