Abstract (en)
[origin: EP0763841A2] The contact arrangement has a fixed and a movable contact part with a contact carrier made of a good electrical conductor, e.g. copper, and a contact plate of a material resistant to burning off e.g. Cu-Cr, facing the other contact part. Each contact carrier (14) has a cylindrical section and an annular section (15,15a,15b) at the end near the contact part. The cylindrical section is connected to the annular section via two mutually coaxial radial straps (16,17). The cylindrical section is divided by an inclined slot (23) in the vicinity of the straps so that the current flows via one of the straps of the annular section to a protrusion which overlaps one of the straps in the switch-on direction and on which the contact plate (19) is attached.
