A vibration and shock-sensitive electrical switch comprising a disc mounted tube with a small snap switch such as a Microswitch centered above the tube end on the disc surface. A switch-actuating wire extends from the switch trigger mechanism through the tube so that when the tube is balanced on its bottom end, the switch is in its first switching position, and when tipped over by vibration or shock, the switch-actuating wire is released and the switch goes to its second switching position. Vibration sensitivity may be adjusted by attaching various diameter or irregular shaped collars on the bottom end of the tube.
