The braking of contact bridge.It is preferred that antivibrator is by elastomeric materials.Antivibrator also can have a stiff base as an alternative
Body, damping material are arranged on the matrix with the synergistic face of antivibrator.Also two can be arranged on each contact bridge
Or multiple antivibrators.It is preferred that damping unit can also have two or more damping elements.It is preferred that to each resistance of buffer unit
Buddhist nun's element is respectively configured the antivibrator being arranged on each contact bridge.
According to another preferred embodiment, damping element is disposed between multiple contact bridges.This is damping unit
A kind of simple structure and low cost implementation.Can additionally realize, be acted on damping element by contact bridge
Power cancel each other out.Thus, it is possible to avoid transmitting the force to parts that are other, can result in undesirable vibration on automobile.
Another preferred embodiment specifies, catalyst and damping unit are arranged in common, sound absorption a shell
In vivo.The switching noise caused due to the break-make of catalyst can be further reduced whereby.Further for contactor arrangement, this is
A kind of particularly compact structure.Especially it is not necessarily each catalyst and arranges and install a single housing, this is on the whole
Simplify the design structure of contactor arrangement.
Another preferred embodiment in, catalyst is disposed on common support unit.By connecing in break-make
The reverse movement of multiple contact bridges of catalyst during tentaculum, is delivered to the preferably phase of the power on common support unit by catalyst
Mutually offset, this again results in reduces the switching noise related to catalyst.
Additionally, subject of the present invention further relates to a kind of method for reducing the switching noise related to contactor arrangement,
The contactor arrangement has the catalyst of at least one contact bridge respectively with least two, wherein, each contact of catalyst
Bridge can be moved back and forth between make position and maximum open position, so as to the break-make catalyst, wherein, multiple contact bridges exist
Move towards when moving to its maximum open position simultaneously and be moved away from each other when moving to its make position at the same time, or instead
It, it is characterised in that multiple contact bridges are braked when its make position and/or its maximum open position is reached with being buffered.
The above-mentioned advantage about contactor arrangement can be correspondingly associated with the method.
