This serves as a temporary energy store and ensures a delay in the energy or force transmission to the one

- the compensating coupling device 36 consists of two rod parts which are arranged one behind the other on a common axis and which are coupled via the spring arrangement 38.
- the two spring elements 42 designed as disc springs are threaded onto a pin-like axle element 40 of one rod part, with a part of a cage 44 of the other rod part extending over one spring element 42 being arranged between the two spring elements 42.
- the compensating coupling device 36 has means for pretensioning at least one of the spring elements 42. These means are in particular directed to pretension the spring elements 42 in an adjustable manner. In the present case, these funds are particularly easy to design.
- the pin-like axle element 40 has an external thread de, which together with at least one nut or other counter element forms a screw connection 46 via which the spring elements 42 can be adjustably preloaded.

- the force of the drive actuator 14 on the main lever 28 causes the shaft 26 to rotate.
- lever 30 - for example via a rigid coupling device - is coupled directly to the main lever 28, there is a direct transmission of force here.
- the force of the spring-loaded drive is delayed due to the angle of rotation of the shaft 26.
- the levers 30, 32, 34 are moved with different starting points or speeds, which leads to a different galvanic contact time of the different poles.
- a coupling is used, which reacts with a delay to the force of the spring accumulator. This coupling is formed by the compensating coupling device 36.
- the coupling 36 is decoupled by spring elements 42 (here cup springs). Any delay, in particular in the millisecond range (ms range), can thus be generated by the spring travel and the subsequent block of the spring elements 42. This is in
