Abstract: A snap-action switch and actuator are disclosed in which a resilient columnar compression member is axially loaded to the point of catastrophic buckling. In one embodiment, the column serves as both an electrical conductor and a contact. In this embodiment, it buckles into contact with another conductive member to complete a circuit. Alternatively, the buckled column may actuate a piezoelectric, optical, or other signal producing means to produce signals used for switching or to close other contacts.

Abstract: A variable capacitance switch element is disclosed in which varying capacitance is effected by increasing the active surface area of a capacitive coupling member in proximity to a second capacitive plate. The structure of the variable capacitive element is such that the capacitance of the device varies in nearly linear fashion with the depression of an actuator member.

Abstract: An elastic diaphragm switch is operated by moving a ribbon along a predetermined path obstructed by a bearing surface on a hammer. A projection on the ribbon presses against the bearing surface on the hammer, displacing the hammer against a spring supporting the hammer. Once the hammer is fully displaced, the ribbon passes beyond the bearing surface releasing the hammer to strike the elastic diaphragm of a switch, thereby momentarily closing the elastic diaphragm switch.
Abstract translation: 通过沿着由锤子上的支承表面阻挡的预定路径移动带来操作弹性膜片开关。 色带上的突起压在锤子上的支承表面上，使锤子抵靠支撑锤子的弹簧移动。 一旦锤子完全移位，色带越过轴承表面就释放锤子，以撞击开关的弹性隔膜，从而暂时关闭弹性膜片开关。
