ABSTRACT:
The invention discloses a device comprising two stationary current-conducting plates with contact members secured thereon and removable contact brush units, each having contact brushes, arrangement for retaining the brushes in the brush unit, a contact member for effecting electric contact between the brush unit and the stationary current-conducting plates, means for securing the brush unit in the device and a handle for mounting and removing the brush unit bodily, the contact surfaces of the contact members of the stationary plates and the contact surface of the contact member of the brush unit being flat and being aligned in a single plane in the operative position of the brush unit, whereby the requirements as to the manufacturing accuracy of these contact-making surfaces become less strict, and the manufacture of the contact members is simplified.
