The Siemens 3SB3201-2KA11 is a 22mm round, black toggle switch constructed from plastic. It features a short knob actuator with two switch positions: O (Off) and I (On). The switch is latching, requiring a specific action to change states, and has an actuating angle of 50 degrees, operating at 11/1 o'clock positions. This unit includes 1 normally open (NO) and 1 normally closed (NC) contact, connected via screw terminals, and comes with a holder. This is a phased-out product, with the SIRIUS ACT 3SU1 series as its successor.

This latching toggle switch is ideal for applications requiring a secure manual control where the switch position needs to be maintained until intentionally changed. Common uses include power control, mode selection, and operational status indication on machinery and industrial equipment. Industries benefiting from this include manufacturing, automation, and electrical panel building.

Expert tip
The 50-degree actuating angle and specific 11/1 o'clock positioning ensure a distinct tactile feedback when changing between the O and I states.
