It physically prevents the switch from being rotated or actuated, providing a reliable means of locking out control circuits during maintenance, servicing, or energy isolation procedures. Electricians and industrial maintenance technicians install this device as part of lockout\/tagout (LOTO) programs to meet OSHA and NFPA 70E requirements. The unit is compact, measuring 0.618 x 0.618 x 0.311 inches, and weighs 0.066 pounds, making it straightforward to add to an existing panel or control station without significant rework.\u003c\/p\u003e\n\u003cp\u003eThis lockout is suited for industrial control panels, machine control stations, and process equipment where 2-position selector switches are used to control motors, circuits, or equipment. It is used in both light industrial and heavy manufacturing environments where energy isolation is required before service work begins. Installation is typically performed by licensed electricians or qualified industrial maintenance personnel as part of a documented LOTO procedure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned specifically for 2-position selector switches in the SIEMENS 3SB series\u003c\/li\u003e\n  \u003cli\u003eEnables lockout\/tagout (LOTO) compliance on control station selector switches\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.618 x 0.618 x 0.311 inches for easy panel integration\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.066 pounds for minimal added load on mounting surfaces\u003c\/li\u003e\n  \u003cli\u003ePrevents unintended or unauthorized switch actuation during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style lockout accessory for 2-position selector switches in the SIEMENS 3SB series control device family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician or qualified maintenance technician.
