ABSTRACT:
A lockout device for an electrical switch has a mounting plate adapted to be attached to the cover plate of the electrical switch. The mounting plate has a pair of mounting apertures which permit it to be attached to the face plate and an aperture formed to circumscribe the switch's actuation member. A blocking plate extends from the mounting plate near its bottom edge. A cover is slidably connected to the mounting plate for movement between an open position at which the actuation member is accessible and a closed position at which the open bottom of the cover abuts the blocking plate so that cover and blocking plate enclose the actuation member. A locking mechanism allows the cover to be locked in its closed position. The cover can be transparent so that the actuation member is visible through the cover when the cover is in its closed position.
