ABSTRACT:
An ON-OFF switch assembly which is lockable for preventing unauthorized use is disclosed. The ON-OFF switch assembly includes an ON-OFF electrical switch mounted within a housing. The ON-OFF electrical switch has an actuator which is shiftable between an ON position and an OFF position. A cover is pivotally attached over the housing between an opened position allowing access to the actuator, a closed position denying access to the actuator, and a run position where the cover is slightly open. The cover has a tab which shifts the actuator to the OFF position when the cover is pivoted to the closed position. A hasp is hinged to the housing. The hasp can be pivoted to extend through an aperture of the cover to enable locking the cover to the housing in the closed position using a padlock, and to retract from the housing to position the padlock clear of the housing to allow the cover to be freely pivoted.
