Abstract
A tilt switch is made by attaching two electrically conductive members to a nonconducting tube and disposing a conductive sphere within the switch. The first and second electrically conductive members are provided with inner cylindrical surfaces of different diameters in order to create an asymmetry that allows the angular conducting range of the switch to be increased without increasing its differential angle at one limit of travel. The first and second electrically conductive members that are used as the end caps of the switch are provided with inner cylindrical surfaces of different diameters. When the conductive sphere is disposed within the switch, it can assume three different positions in relation to the first and second electrically conductive members. A first position is defined by the sphere being in contact with both electrically conductive members and supported by contact points of both members. The second position is defined by the sphere being in contact with a first contact point but in noncontact relation with a second contact point. The third position is defined by the sphere being in contact with the second contact point but being in noncontact relation with the first contact point.
