Schneider Electric 9001KS43K5R Harmony 9001K Key Switch Head Metal 30 mm 3-Position Key E10 Selector Switch

The Schneider Electric 9001KS43K5R is a 3-position Harmony 9001K key-operated selector head using Ronis key E10, withdrawable at the centre position. Supplied as a basic element without a contact block, it mounts on a 30 mm panel cut-out and pairs with a 9001K contact block to lock a three-state function to key holders.

Selection Notes

Centre-position key withdrawal (Ronis key E10) lets an operator lock the switch at its neutral/off state while leaving it free to move between the two outer positions when the key is inserted, which differs from the 9001KS11K1R’s left-only withdrawal and suits applications where the neutral state is the one to secure. Cam profile 3 matches the same 3-position 9001K contact blocks used on the handle-operated 9001KS43FB. As a head-only basic element it still needs a separately ordered 9001KA1-compatible contact block to complete the switching function.
