ABSTRACT:
A sensor for outputting a signal in response to swinging of a pendulum when acceleration acts upon the sensor is provided with a tilting mechanism for tilting the frame of the sensor with respect to a support therefor, and a control for actuating the tilting mechanism so as to change position that the pendulum occupies, relative to an output signal switch, in the absence of applied acceleration. As a result, the swinging distance of the pendulum from its initial position to the position at which the output signal is produced is changed, thereby changing the corresponding value of acceleration which prevails at the time of signal output.
