摘要： Disclosed is a device that can be placed on the lever arm of a switch and locked to prevent the switch from being turned on. The device comprises a rigid body having a clasping device for removably fixing the rigid body to the lever arm, an aperture through the rigid body in which the shackle of a lock can be placed, positioned so that when the shackle is in the aperture access to the clasping device is blocked, and a bracing portion which contacts the switch to prevent its lever arm from being rotated when the device is attached thereto.
