Abstract
A locking device is insertable into a cover opening adjacent to a handle of an electrical switch to occupy the space in the cover opening for resisting movement of the handle. The locking device has two pivotally connected members. The pivotal movement of the members creates a collapsed condition or an expanded condition for the locking device. The pivotal members have a transverse opening which are alignable relative to each other when the locking device is in its expanded condition. The locking device is inserted into the cover opening when the pivotal members are collapsed. In a first embodiment, a handle shroud member has an opening for receiving the handle and a second member has leg means along its base for engaging an undersurface around the cover opening when the locking device is in its expanded condition. In a second and a third embodiment, both pivotal members have leg means for engaging undersurfaces around the cover opening when the locking device is in its expanded condition. Once the apertures of the members are in alignment, a padlock is inserted therethrough for retaining the locking device in its expanded condition in the cover opening thereby resisting movement of the handle of the electrical switch.
