Selection Notes
The XB4BD21 gives 2 fixed, stay-put positions for a simple on/off or mode-select function with a single 1 NO contact. Where the application needs an intermediate centre position or a second contact, the 3-position XB4BD33 (stay put) or XB4BD53 (spring return to centre) in the same range are the choice instead of adding a separate selector.
