The XB2-BG21 is a 2-position self-locking key switch for industrial control panels, machinery, and equipment where access must be restricted to authorised personnel. Turns and latches in the selected position — the key can only be removed in one defined state, ensuring the switch cannot be left in an unsafe or active condition unattended. Standard 22mm panel mount, compatible with XB2 series contact blocks.

Common Questions
What contact block does this switch use?
The XB2-BG21 head is compatible with standard XB2 series contact blocks (NO, NC, or NO+NC combinations). The contact block determines the electrical configuration — the switch head itself provides the mechanical key-operated actuation. Contact blocks are sold separately.
What's the difference between the XB2-BG21 and the LAY37-11Y2?
Both are 2-position self-locking 22mm key switches with key-removable-in-one-position functionality. The XB2-BG21 uses the XB2 (Schneider-compatible) platform and is typically supplied as a head only, requiring a separate contact block. The LAY37-11Y2 comes pre-fitted with a 1NO+1NC contact block. Both use the same 22mm panel cutout.
Please note: Only 1 in stock. Contact block compatibility: standard XB2 series. For AC mains wiring, installation by a qualified electrician is required.
