ABSTRACT:
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.
