Safety interlock switch system

摘要

An improved safety interlock switch device incorporated onto a machine with internal moving components. The device is mounted adjacent a cover which shields the internal components of the machine when the cover is in a closed position. When the cover breaks contact with the switch, electrical circuit controlling the internal moving components is broken such that movement ceases in the interior of the machine. This type of system protects operators who can be injured by moving internal components while also preventing destruction of the internal components caused by contact with external elements while still in motion. The present invention lengthens the time delay between the break in contact of the cover and the deactivation of the electrical circuit controlling power to the internal movable components.
