ABSTRACT:
A tool for removing a snap-in bushing type toggle switch or the like from a hole in a mounting panel. The tool is molded of plastic material and is provided with a spring-biased self-opening slidable chuck snap-in assembled within a compressor tube and is adapted to squeeze the snap-in collar or skirt of the snap-in bushing so that it becomes released from the mounting panel. The outer compressor tube having a mushroom handle at one end is adapted to slide forwardly over the chuck to compress or squeeze it and the snap-in collar therewithin. A spring-biased ejector pin slidable within the chuck is depressed by the toggle lever of the switch and is loaded by its spring compressed by the compressor tube and serves to snap the switch from the panel hole upon release of the snap-in collar.
A first version has an integrally-molded resilient lug on the chuck that snaps out into an elongated slot in the compressor tube wall to snap-in assemble the chuck within the compressor tube for limited sliding movement. A second version has an integrally-molded hook on the chuck that slides along a groove in the compressor tube to engage a catch to snap-in assemble the chuck within the compressor tube for limited sliding movement.
