Embodiment Construction

[0028] figure 1 A schematic sketch of a module 100 according to the invention is shown. In addition, in figure 1 The rotary drive 200 and the undervoltage release 300 are shown in . The handle 310 of the electrical switch turns on or off the electric current by linear movement from the "ON" position into the "OFF" position or from the "OFF" position to the "ON" position. The rotary drive device 200 converts the rotation of the rotary handle 10 into the linear motion of the handle 310 of the electric switch. For example, a transmission 220 and a slide 230 which moves the handle 310 of the electrical switch can be provided for this purpose.

[0029] figure 1 Also shown is a module 100 according to the invention which is mounted between the rotary drive 200 and the rotary handle 10 and which comprises an auxiliary switch 110 . When turning the handle 10, for example, according to figure 1 When the arrow in is turned from the "OFF" position to the "ON" position, the auxiliar...

Abstract

The invention relates to a rotary drive of a module for an electrical switch, wherein the rotary drive is actuated by means of a rotary handle in such a way that the handle is turned so that the axis of rotation of the rotary drive moves between at least two switch positions, wherein the The module can be installed between the rotary drive device and the rotary handle and comprises at least one auxiliary switch, wherein, when the module is mounted between the rotary drive device and the rotary handle, when the rotary handle is rotated, when reaching one of the At least one auxiliary switch is switched before the switch position.

Description

technical field [0001] The invention relates to a module for a rotary drive of an electrical switch, an electrical switch with such a module, and a switching method for the electrical switch. Background technique [0002] When the compact power switch is turned off, the circuit of the undervoltage release should normally be disconnected from the voltage source using an auxiliary switch for all poles. In this case it must be ensured that the circuit of the undervoltage release is connected to the voltage source again when the "OFF" position of the compact power switch handle is left. [0003] To solve this problem, for example, auxiliary switches can be installed in compact power switch boxes in addition to the undervoltage release. However, this solution requires additional volume in a compact power switch box, which detracts from the space for additional internal accessories. There must also be a defined travel distance between the "OFF" position leaving the compact power...
