PCT No. PCT/DE92/00687 Sec. 371 Date May 16, 1994 Sec. 102(e) Date May 16, 1994 PCT Filed Aug. 26, 1992 PCT Pub. No. WO93/06612 PCT Pub. Date Apr. 1, 1993.A method for determining mechanical parameters of an electric switching device exposed to environmental influences in which a measuring transmitter is provided for detecting the speed of a component of the drive means of the switch device at at least two consecutive times. In the case of vacuum power switches, the time of contact of the switch members and the time of the latching in the switched-on condition are preferably considered. If measurement values from comparative measurements of a given number of switches are available, the maximum intensity of a given environmental influence at which test sample can reliably operate is determined from a measurement of a test sample under normal environmental conditions.
