A tilt switch is provided which comprises a plurality of rails which are connectable in electrical communication with circuit points of an electrical circuit. The preferred embodiment of the present invention comprises first, second and third rails which are associated in preselected pairs to define first and second tracks. In each of the two tracks, the distance between the preselected pair of rails is variable along the length of the tracks. This causes a spherical weight which is supported by a preselected one of the first and second tracks to alternatively fall out of contact with one rail and fall into contact with another rail. If first and second rails are connected to appropriate circuit points, the device can be used as a tilt switch to make and break electrical contact between appropriate components in response to changes in angular disposition of the switch.
