Abstract: A gravity actuated electrical switch in which electrical contact is made and then broken as the switch is moved from a horizontal to a vertical position consisting of a container within which is disposed a metallic rollable member, a vertical wall member within the container of a height to allow the rollable member to pass over the top of the wall, a pair of electrical contacts capable of being bridged by the rollable member positioned against the wall, and a horizontal ramp member forward of the contacts. Motion of the switch causes the rollable member to move forward, bridge the contacts and then fall to the forward end of the container. Return motion causes the rollable member to move back along the ramp and pitch over the wall without again joining the contacts.
