ABSTRACT:
The invention provides a safety switch device which is particularly adapted to increase the reliability a food processor. The switch has a piston which is slidably mounted inside a bore formed in a tapering projection in the base of the food processor so as to protect electrical circuitry inside the food processor from ingress of liquid or powder substances. The piston is spring biased and when depressed touches a contact device which is wired between an electrical power source and the food processor motor such that depression of the piston allows operation of the food processor motor. In operation the piston is depressed by a push-rod only when the bowl and the lid are properly installed on the food processor base. The piston is fitted with O-ring which resiliently seals between the piston and the bore. The piston is also formed with a skirt which surrounds and overlies a support for the contact device so that any liquid or powder substances which seep by the O-ring are directed away from the contact device.
