Siemens 3SB02-2-LHC1 Selector Switch With Key

Siemens 3SB02-2-LHC1 Selector Switch With Key is a two-position, key-operated selector switch that uses a spring-return mechanism to return to the left position after actuation. The unit includes a key to secure or disable the selected setting, supporting controlled operation and preventing accidental changes during setup or maintenance. Intended for panel mounting in industrial control circuits, this switch provides a straightforward method to select between two circuit paths or control functions and then automatically revert to its default state when released, a behavior described by the "spring return R to L" specification. As a genuine Siemens component, it is designed to withstand the rigors of typical automation environments and to integrate with compatible control hardware in expansion-friendly control panels. The 3SB02-2-LHC1 is well-suited for applications such as mode selection, start/stop sequencing, and safety interlock schemes where a non-latching, momentary selector is desirable, and the included key adds an extra layer of operational security for maintenance windows or restricted access scenarios.
