Three-Position Dual-Latching Key Selector Switch Head

This is the head unit of a key-operated selector switch assembly, designed to pair with contact blocks and a mounting frame to form a complete switch. The three-position dual-latching action holds in left, center, or right after the key is turned and removed — the key can be withdrawn in any position, locking the selection in place and preventing unauthorized changes. This makes it suitable for control panels where mode selection must be restricted to authorized personnel only. The anti-rotation boss prevents the head from turning in the panel cutout under repeated use. IP65 as standard, extendable to IP66.

FAQ:

Q1: Does this head come with contact blocks included?
No, this is the head unit only. Contact blocks and mounting frame are sold separately and need to be ordered together to assemble a complete switch.

Q2: Can the key be removed in all three positions?
Yes. The key can be withdrawn in the left, center, and right positions, locking the switch in the selected state and preventing unauthorized operation.

Q3: Is this head compatible with standard contact blocks?
Yes. It follows standard Φ22mm interface dimensions and is compatible with ACXION contact blocks. If combining with third-party contact blocks, confirm dimensional compatibility before ordering.
