An emergency stop button, also known as an E-Stop, is a fail-safe control switch designed to ensure safety for both the machinery and its operator. The purpose of the emergency push button is to stop the machinery quickly where there is a risk of injury or when the workflow needs to be halted.
To minimise risks, all machinery must be equipped with an emergency stop button. These buttons are typically red, often set against a yellow background, making them easy to identify in an emergency.

Emergency stop push button switches are used in various industries, including industrial, commercial and public facilities, as follows:
In Hong Kong, emergency stop push button switches must adhere to strict safety standards to ensure reliable operation in critical situations. These standards, often aligned with international guidelines like IEC 60947-5-5 and ISO 13850, dictate specific requirements for button design, functionality, and installation. This includes specifications for colour (red button with a yellow background), shape (easy to activate), and contact type (normally closed). Adhering to these standards is crucial for minimising risks and ensuring worker safety in industrial and commercial settings.
When choosing emergency stop switches, consider factors such as visibility (for easy identification), accessibility (to be within reach in emergencies), and durability (to withstand harsh environments). Ensure the switch meets safety standards and is compatible with the machinery. Additionally, consider response time, ease of activation, and weather resistance if the switch will be used in outdoor or extreme conditions.
