Selection Notes
Because the key withdraws in any of the 3 positions, the XB4BG03 suits an application where an authorized operator needs to lock the panel in whichever mode was last selected, not only a single home position. Where the key should only come out at one fixed mode (for example to force the panel back to a safe state), the left-hand-withdrawal XB4BG21 or centre-withdrawal XB4BG33 in the same range are the correct choice instead.
