ABSTRACT:
A lockable switch for an electric cord comprising a housing, a switch having "on" and "off" positions retained within the housing and having a control operative from outside the housing for moving the switch between its "on" and "off" positions, and terminals for electrically engaging and connecting the switch with an electric cord received within and extending through the housing. A key-actuated lock having locked and unlocked conditions, and an interengagement device actuated by the lock for engaging the switch and locking the switch against movement when the lock is in its locked condition are also contained within the housing. The lock which is rotatable has a cam element provided by an extending tumbler which rotates with the actuation of the lock between its locked and unlocked conditions and actuates the interengaging device toward and away from the switch for engaging and disengaging the control and locking and unlocking the switch.
