Abstract:
A switch device which comprises a first contact (1), that is designed to be electrically connected to a first conductor (101) of a power line and a second contact (2), that is designed to be electrically connected to a second conductor (102) of said line, the first or the second contact being mounted in a displaceable fashion, so that said first and said second contacts (1, 2) alternately assume a mutual adhesion position, in which adhesion position electric connection is generated between said first and said second conductors of said power line, or a mutual retraction position, in which said two conductors (101, 102) are electrically disconnected from each other. The first or the second contact has a contact surface which is formed of a plurality of separate contact zones (Zi), which are connected in parallel to the conductor connected to the corresponding contact, and each of which adheres independently of one another to the cooperating second or first contact.
