Abstract: A safety lock for a door of a household appliance, preferably of a washing machine, includes a housing on one end of which there is a mechanical assembly of the door lock, on the other end there is an assembly of the electric switch used to reach closed or interrupted electric circuit, into which also a part of a programme selection switch is included, whereby the assembly of the door lock and the assembly of the electric switch are mutually linked by a slider, which is designed in a way that its lug engages with the hook of the appliance door, when the hook is in the guide, so that upon manual closing of the appliance door the hook pushes the slider towards the assembly when entering the guide.

Abstract: An upper part of an electric switch casing is positioned over a lower part of the casing and is form-locked therewith. Between said parts a first chamber, in which voltage carrying connecting pieces are mounted, is formed between peripheral vertical side walls of the lower part and a vertical partition of the lower part. The width and the height of a first gap between the peripheral vertical side wall of the upper part of the casing and the peripheral vertical side wall of the lower part of the casing as well as of a second gap between the vertical partition projection of the upper part of the casing and the vertical partition of the lower part of the casing are such that the capillary elevation of liquids used in household occurring in said gaps is lower than the height of said gaps the width of said first and second gaps being kept as low as possible.
