Abstract: A tool for compressing a safety interlock switch on appliances is disclosed. The tool comprises of a first portion having an upper end and a lower end and a second portion connected to the first portion by a hinge means. At least one magnet may be secured to the first portion and at least one ferrous portion may be integrated within the second portion. The at least one magnet may be configured to fixedly contact with a smooth metal surface of the appliance while compressing the safety interlock switch with the second portion thereby enabling technicians to safely diagnose, maintain, and repair the appliances. The tool prevents the inadvertent disablement of the switch by mechanically blocking a door of the appliance from closing. The tool can be easily opened with one hand, fits easily in a pocket and prevents unwanted attraction of ferrous objects in the closed position.
