Abstract
An electric switch which can be locked using any possible lock to either prevent or ensure the flow of electric power to an electrical apparatus. The switch has a toggle-handle that a bar from a lock can be fitted into and immobilize the toggle-contactor, preventing the toggle from being moved. Thus the switch is prevented from being turned on or turned off. The switch is intended to be placed into a power cord and can be sold with a device or added later.
Claims21
An electrical switch device comprising:
- an electrical switch with an open position and a closed position;
- a toggle-handle attached to the electrical switch so that the toggle-handle could move the electrical switch between the open position and the closed position and maintain the electrical switch in that position;
- at least two holes in the toggle-handle;
- a lock bar;
- a locking means to lock the lock bar and prevent movement of the lock bar;
- a housing for the electrical switch and the toggle-handle with at least one hole in the housing that substantially lines up with at least one hole on the toggle;
- so that the lock bar is attached to the electrical switch device by fitting the lock bar into both a hole in the housing and a hole in the toggle-handle and the locking means immobilizes the lock bar and thus the toggle-contactor and thus fixing the electrical switch in either an open or closed position.

An electrical switch device kit comprising:
- an electrical switch with an open position and a closed position and with two wire-connectors;
- a toggle-handle attached to the electrical switch to that the toggle-handle could move the switch between the open position and the closed position, with at least two holes in the toggle-handle;
- a lock bar;
- a locking means to lock the lock bar and prevent movement of the lock bar;
- a housing for the electrical switch and the toggle with at least one hole in the housing that substantially lines up with at least one hole on the toggle-handle;
- an electrical wire of an electrical circuit;
- so that the electrical wire of the electrical circuit can be cut and stripped of insulation such that one of the newly-created wire-ends can be electrically attached to one wire-fastener of the electrical switch and the other wire-end attached to the other wire-fastener of the electrical switch, so that when the electrical switch is in a closed position, electricity can flow in the electrical circuit;
- so that the lock bar is attached to the electrical switch device by fitting the lock bar into both a hole in the housing and a hole in the toggle-handle and the locking means immobilizes the lock bar and thus the toggle-contactor and thus fixing the electrical switch in either an open or closed position.
