16/19/22mm Red Mushroom Head Emergency Stop Button Switch

Product Overview
The 16mm, 19mm, and 22mm red mushroom head emergency stop button switches are critical components in industrial safety systems, each tailored to specific operational needs.

The 16mm model is ideal for compact applications, offering a space-saving design without compromising on reliability. It typically features a 3-pin configuration with 1NO1NC contacts, supporting voltages up to 250V AC and currents up to 3A.

The 19mm version provides a balance between size and functionality. It often includes a 3-pin latching mechanism with 1NO1NC contacts, rated for 250V AC and 3A. The slightly larger head enhances visibility and user interaction, making it suitable for a wide range of machinery and control panels. 

The 22mm model is designed for high-demand environments. It typically offers a 4-pin configuration with 1NO1NC contacts, supporting higher currents up to 10A and voltages up to 660V AC. The robust construction and larger head size ensure durability and easy activation.
