Abstract (en)

[origin: EP1357567A2] The device has a motor driving a drive shaft in the tensioning direction, a cam plate coupled to the shaft for driving a tensioning element during a tensioning phase and at least one motor control plate coupled to the shaft. The couplings between the cam and control plates and drive shaft are designed so the cam plate can lead the control plate at least slightly in the tensioning direction after passing through the tensioning phase. The device (19) has a motor (21) driving a drive shaft (22) in the tensioning direction, a cam plate (24) coupled to the shaft for driving a tensioning element during a tensioning phase and at least one motor control plate (26) coupled to the drive shaft. The couplings between the cam plate and control plate and the drive shaft are designed so that the cam plate can lead the control plate at least slightly in the tensioning direction after passing through the tensioning phase. AN Independent claim is also included for the following: (a) an electric switch, especially a low voltage power switch.
