An electrical tilt switch includes a generally cylindrical cap member having a hollow interior with an internal inwardly extending ridge positioned a significant distance above its lower edge, a flat, generally cylindrical base member having a concave dished upper face, an annular insulating member interposed between the base and cap and fastened to each, electrical leads attached to the base and cap members, and a spherical contact member carried on the dished surface and movable against the ridge when the switch is tilted to a specified angle. For severe environmental conditions the preferred material for the cap, base and spherical contact member is a K Monel alloy.

An electrical tilt switch including a pair of electrical contacts and moveable means for making and breaking electrical continuity between said contacts, characterized in that said switch comprises a generally cylindrical cap member having a ridge extending internally of its internal sidewall and spaced a significant distance from its bottom edge such that said sidewall extends only a part of the height of said cap member, the internal top surface of said cap extends only a part of the distance from its center toward said internal sidewall, and a radially inwardly extending surface extends from said internal sidewall, said ridge being form in a generally “S”shaped convex surface from said top surface to said radially inwardly extending surface, a generally cylindrical base having an upper face having a smooth concave dished surface, an annular insulating member of generally cylindrical shape having an internal surface fastened to said base member and an external surface fastened to the internal sidewall of said cap member, electrical leads attached to said cap and base members, and a spherical contact member carried on said concave dished surface and moveable against said ridge when said switch is tilted from the vertical by a specified amount, thereby closing said switch.
