Abstract (en)

[origin: EP0805464A2] The stepping switch has a number of stationary contacts extending along a linear switch path for cooperating with a sliding switch mechanism. This has a directly driven carriage provided with a mechanical auxiliary contact (HK) and a drawn element with a mechanical main switch contact (SK). The auxiliary contact cooperates with a contact rail (KS) coupled to the load connection (L) via a resistance (R) and a vacuum switch (VH), with 2 further vacuum switches (VS,VL) connected in series between the main switch contact and the load connection.
