Siemens 52SA2HABJ2K2 Selector Switch Maintained 4 Position

Siemens 52SA2HABJ2K2 is a four-position, maintained selector switch designed for panel-mounted control in 30 mm installations. The US2 variant features a metal housing with a short-lever operator and cam code H, a white insert, and non-illuminated operation. It provides a 4PST-2NO/2NC contact arrangement—two normally open and two normally closed contacts—with left and right throws specified as 1NC+1NO on each side for two independent poles in a single unit. Rated up to 60 A at 110 VAC and 12 A at 500 VAC, it is UL-listed (UL file E22655) for industrial use and suited to mid-range control circuits. The unit is intended for panel mounting in a 30 mm footprint and is commonly employed in machine control panels and process lines to select operating modes or control sequences, offering reliable, maintained positioning without continuous actuation.
