Siemens 3SB02 3MKBP 22mm 3 Position Maintained Selector Switch

Siemens 3SB02-3MKBP is a 22 mm, round panel-mounted selector switch with a three-position maintained action and a black knob, built for durable operation in industrial control panels. Designed for manual selection across three discrete states, the switch provides a lockable position that remains until the operator changes it, making it suitable for mode selection, sequencing, or operating-state choices in automation equipment. Its compact 22 mm footprint fits standard panel cutouts and integrates with Siemens’ 22 mm selector switch lineup for compact control solutions. The 3MKBP suffix identifies the black-knob configuration of this maintained 3-position model, aiding quick identification on crowded control panels.
