PCT No. PCT/DK94/00316 Sec. 371 Date Feb. 22, 1996 Sec. 102(e) Date Feb. 22, 1996 PCT Filed Aug. 23, 1994 PCT Pub. No. WO95/06259 PCT Pub. Date Mar. 2, 1995An apparatus for detecting the malfunctioning of an accelerometer (4), where a test signal in the form of a pulse is transmitted from a test signal generator (3) to the accelerometer (4) by a change-over switch (1,2) capable of performing a change to transmit the response signal from the accelerometer (4) to an analyzing circuit (8) so as to be subjected to a malfunction detection. The change-over switch (1, 2) is adapted to alternately connect the accelerometer (4) either to the test signal generator (3) or to the analyzing circuit (8). A particularly simple circuit is obtained wherein the response signal in the form of a ringing is not connected to the analyzing circuit until after the pulse has been transmitted by the test signal generator.
