Abstract (en)

[origin: EP1202303A2] The switch contact arrangement has contact levers that are subjected to the different spring forces of various springs. The outer contact levers, which are arranged in a multiple contact system on a contact bearer, are subjected to higher contact forces than the inner contact levers. The contact forces increase continuously in small steps from the inner to the outer levers.
