Abstract
The utility model relates to a safety switch used in a household electrical appliance, which is installed at the bottom of the household electrical appliance. The safety switch comprises an elastic button, a static contact, and a moving contact positioned below the static contact and connected with the upper end of the spring button. The static contact is connected with one end of the household electrical appliance, and the moving contact is connected with the other end of the household electrical appliance; the elastic button passes through and protrudes out of the bottom of the household electrical appliance; and when the elastic button is pressed and the lower end thereof is flush with the bottom of the household electrical appliance, the moving contact contacts with the static contact. During the use of the safety switch provided in the utility model, in case the household electrical appliance suddenly falls down, the elastic button is bounced and the moving contact is separated from the static contact, so that the household electrical appliance is turned off, thereby ensuring personal and property safety.
Description
