Abstract

Electrical interlock for front doors of washing machines or dishwashers to prevent switching on of the mains supply whilst the doors are still open has a clevis provided at one end of a fulcrum lever held in either the open or closed position by a spring biased toggle lever. Associated with the clevis is a bell crank lever whose one arm (I) is biased by a torsion spring to obturate the clevis with the lever in the open position. The other arm of the lever abuts a stop fast with the door. During closing of the door the pawl of a locking member which is fast with the machine housing first causes displacement of the arm (I) to progressively uncover the clevis which only following complete engagement with the pawl causes the lever to pivot into its other, mains energising, toggle position.
