Schneider Electric Harmony 3-position Key Switch Head, Maintained, 22 mm Cutout

This head with key (key no.455) provides a versatile interface for controlling your machines. It is easily installed and replaced on compatible complete key selector switch units. It provides a secure manner for authorized staff to switch between process or machine operating modes. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66. It makes it ideal for operation in harsh environments.

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.
