Hätäkatkaisin

Hätäkatkaisin, also known as an emergency stop button or E-stop, is a safety mechanism used on machinery and equipment to quickly shut down operation in an emergency situation. Its primary purpose is to prevent injury to personnel or damage to equipment when an unexpected hazard arises.

These devices are typically brightly colored, most commonly red, and have a mushroom-shaped button for easy and immediate activation. They are designed to be pressed firmly and can often be reset by twisting or pulling the button, or by using a key. The placement of hätäkatkaisimet is crucial, with multiple buttons often installed on larger machines to ensure they are accessible from various positions.

The function of a hätäkatkaisin is to interrupt the power supply to the machine's drive system, bringing it to a halt as quickly as possible. This immediate shutdown is vital in scenarios such as entanglement, unexpected movement, or any situation where continuing operation would pose a significant risk. Regular testing and maintenance of hätäkatkaisimet are essential to ensure their reliability and effectiveness. Their presence is a fundamental aspect of machine safety regulations in many industries.
