  • Description

The Schneider Electric XB7NG21 is a Harmony XB7 monolithic key selector switch for 22 mm panel cutouts, using key no. 455 to restrict a stay-put 2-position, 90-degree, 1 NO circuit to authorized operators. The key withdraws from the left-hand position, and screw-clamp terminals plus an IP65-rated plastic body (UL type 3/12) suit industrial control panels.

Selection Notes

Choose the XB7NG21 over a standard (non-keyed) XB7ND21 stay-put selector when the 2-position function must stay locked out from unauthorized operators between shift changes; the key 455 profile only withdraws from the left-hand position, so the circuit stays in that state once the key is removed. The single 1 NO contact suits an enable/permissive signal to a PLC input rather than switching line power directly.
