Abstract
Electrical switch lockout devices for selectively maintaining a position of an electrical switch on an electrical switch base are described. The electrical switch lockout devices include a base adapter configured to be fitted around the electrical switch base, a housing that is moveable between an engaged position and a disengaged position, and a locking mechanism. The housing includes walls, an opening on one side of the housing, a first lateral lip disposed on a first edge of the opening, and a second lateral lip disposed a second edge of the opening. The first lateral lip and the second lateral lip are configured to engage and disengage with the base adapter in the engaged and disengaged positions, respectively.
