ABSTRACT:
Switch lockouts are disclosed which may be fixed to a single toggle switch, a ganged toggle switch, or a similarly acting switch, valve operator, or similar structure to prevent the switch from being operated. The lockout comprises a projection and abutments which engage the switch handle and the body of the switch. The projection extends into an aperture of the handle in one embodiment, or under the crossbar of a ganged handle in another. The abutments, and in some instances the projection, embrace the handle and prevent substantial rotation of the handle with respect to the lockout, or of the lockout with respect to the switch body. Thus, the switch handle, switch body, and lockout are fixed substantially immovably together.
