Question

CAN SOMEONE PLEASE REPHRASE THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A commonly used sensor is the electromechanical "gas dampened ball and tube" design. The sensor is nothing more than a small tube with a switch at one end and a gold plated steel ball at the other, held in place by a small magnet. When the sensor receives a hard enough jolt to knock the ball loose from the magnet, the ball rolls down the tube, hits the switch and closes the circuit. The tube is slanted upward so the ball should return to its original position after an impact.

Answer 1

A sensor that is commonly used is the electromechanical design of a "gas dampened tube and ball." It is a sensor with nothing else but a tube that is small with  a small switch at one of the ends and a steel ball that is gold at the other end. Its all held together by a magnet. If and when it receives a jolt that is hard enough, it can knock the magnet and loosen the ball and makes it roll down the tube and hit the switch to close the circuit. It will return to its original place because of the slanted design of the tube.

Answer 2

One of the most commonly used sensors is the electromechanical "ball and tube" design. The ball and tube  design uses a sensor that activates a small  metal ball whenever it receives a hard enough jolt from it's magnet. Whenever it does, it's gold plated ball rolls down the tube and hits a small switch which then closes the circuit that it is connected to. If you want to reset the ball and tube, just tilt the tube to the other side and the ball will go back to its original position.
