Abstract
A self-adjusting lid switch for a type washing machine connects the switch to the lid by means of a slip joint composed of intermeshing toothed plates spring biased together. The first time the washing lid is closed the plates slip with respect to each other so that the switch is just actuated when the lid is closed. In this way a limited and predictable lifting of the lid de-actuates the switch so as to stop the washing machine before access to the washing machine tub is obtained.
