The electeromechnical "gas dampened ball and tube" design is a commonly used sensor. This sensor is simply composed of a small tube with a switch on one end and a gold plated steel ball on the other end the items on both end are held in place by a small magnet. When a hard enough jolt is received to knock the ball loose from the magnet, the ball rolls down the tube and hits the switch which closes the circuit. After the circuit is completed the ball should return to its original position after a impact because of the tubes upward slanted position.
A sensor that is commonly used is the electromechanical design of a "gas dampened tube and ball."

It will return to its original place because of the slanted design of the tube.
