Abstract
A contact element holder, in particular a brush holder for commutator or wiper ring machines, has a carrier that can be secured to the machine housing and at least one quiver, held on the carrier and pointing toward the rotor, for displaceably receiving a contact element, and also has decoupling elements which are disposed between the carrier and the quiver. To achieve good noise decoupling of the contact element from the machine housing and, in use in a commutator machine, for assuring good commutation quality, the decoupling elements are embodied and disposed such that the at least one quiver is capable of executing only a limited rotational pivoting distance about the rotor.
