The LAY37-11Y2 is a 2-position latching key selector switch for industrial control panels where authorised-only operation is required. Once turned to a position the switch stays latched — no need to hold it. The key can only be removed in one defined position, preventing unauthorised or accidental mode changes. Rated 10A / 660V AC with a 1NO + 1NC contact block.

The 1NO + 1NC configuration gives you simultaneous access to both the active and inactive contact states.

Common Uses
Machine start/stop — restrict operation to key-holding personnel

Conveyor & motor control — reliable latching action for run/stop circuits
Industrial automation & PLC input switching
Security panels & access control systems
Common Questions
In which position can the key be removed?
The key can only be removed in one defined position (typically the OFF or safe state). This ensures the switch cannot be left in an active or unsafe state without the key present — a critical safety feature for machine lockout and authorised-access applications.
Is this compatible with standard LAY37 / XB2 series enclosures?
Yes — the LAY37-11Y2 uses the standard 22mm panel cutout and front-fixing mounting format, making it compatible with LAY37 and XB2 series panel enclosures and mounting hardware.
Please note: Only 1 in stock. For AC mains wiring, installation by a qualified electrician is required.
