It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66. It has a plastic bezel, this makes it ideal for applications requiring good resistance to chemical agents and/or double electrical insulation. It is designed to fit in a standard 22mm cutout, ensuring compatibility when installing in pre-existing machinery. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product. Key removal allowed in only one of the positions, allowing for advanced interlocking between various parts of a machine or process, while limiting human errors.

Schneider key switches are manually operated by turning a key. Various switch versions are available enabling the operator to gain a clear visual indication of the switched position and the commands required for the electrical control of equipment.

Keys can be removed or may "stay-put" in different positions (switch type dependent). Please refer to the manufacturers datasheet for specific details. Some models have spring return features, that enables the key to activate the switch, then return to the original 'home' key position.
