<p>Such switches have current connections for contacts. One contact may be a fixed contact and the other contact may be a mobile contact. A drive opens the mobile contact when a predetermined electric current intensity is exceeded. The electric drive is a thermoelectric drive. For that purpose, the contacts (2, 3) are arranged in a closed housing (1) made of an insulating material and a disk-shaped resistance (4) is arranged between the contacts (2, 3). A switch of this type may also be advantageously designed as a bistable limiter.</p> |
