Allen-Bradley 800EM-KR21 Selector Switch Maintained is a 22.5 mm, two-position, key-operated switch with a non-illuminated, round metal operator designed for panel mounting in industrial control enclosures. The maintained (latching) design holds the selected position until the key is rotated to switch states, and the KR21 variant specifies a keyed, two-position configuration. Rated for use in harsh environments with a NEMA 4/13 protection profile, this switch is suited to dusty or damp industrial settings where reliable two-state control is required.
