A contact assembly for electric switches has a single disconnecting point 19 and a blade 11 pivoted on a stationary axis 12 disposed between the disconnecting point and that part of the contact assembly which continuously connects the blade 11 to one of the fixed terminals 14. Each fixed terminal 14, 15 comprises a group of spring-clip contacts. The end 18 of the blade 11 has saw cuts 16 to reduce electrodynamic repulsion.
