Selector switches have IP 66 ingress protection Selector switches with IP 66 ingress protection feature a re-designed internal mechanism for improved feel and feedback, with added functionality and improved ergonomics. As part of Telemecanique's continuous improvement programme, their world leading Harmony Selector Switches with IP 66 ingress protection have undergone a transformation, with added functionality and improved ergonomics. Featuring a re-designed internal mechanism for improved feel and feedback, the number of switching options has been increased by enabling actuation of three contact blocks per row.

Concurrently, the Harmony key switch ranges have been further upgraded and now feature a sliding shutter to protect the key aperture, and plastic encapsulated keys for better grip.

These improvements come at no extra cost, and have been incorporated in both Harmony style 4 (metal) and Harmony style 5 (all insulated) ranges.

All are backwardly compatible with the existing Harmony products they replace, and feature IP66 degree of protection.
