Abstract

The invention is directed to an overcurrent-protective switch for household appliances such as a vacuum cleaner. The snap switch has a housing in which a contact mounting unit is mounted at one end of the housing and contains one of two current terminals of the switch. The other current terminal is mounted at the other end of the housing and is configured to define a contact-engaging surface. A resilient interrupting contact member is fixedly connected to the one current terminal and has a metal center strip by means of which it is held in one of two end positions. In the first end position, the contact member is held in contact engagement with the contact-engaging surface of the other current contact terminal and, in the second end position, it is disengaged from the contact-engaging surface. When the center resistance strip is cool, the contact member is in its first position and the current circuit between the two current terminals is closed. On the other hand, when excessive current passes through the center strip, the latter heats and expands causing the contact member to snap over into the second position to interrupt the current circuit between the two current terminals. A reset plunger returns the contact member to its first position.
