Schneider Electric 9001KS11K1R Harmony 9001K Key Switch Head Metal 30 mm 2-Position Key 455 Selector Switch

The Schneider Electric 9001KS11K1R is a 2-position Harmony 9001K key-operated selector head using key number 455, withdrawable in the left position. Supplied as a basic element without a contact block, it mounts on a 30 mm panel cut-out and pairs with a 9001K or 9001SK contact block to restrict mode changes to key holders.

Selection Notes

Key number 455, withdrawable only in the left position, means the key can be removed to lock the switch in that position and restricts the second position to authorized personnel holding a matching key — the reason to pick a key head over the handle-operated 9001KS11FB where mode changes must be controlled. Cam profile 5 matches the 2-position 9001K contact blocks (including 9001KA1 and 9001KA2), so the same contact block family used on the handle version also fits this key head. As a basic element it still needs a separately ordered contact block to complete the switching function.
