Abstract: A momentary membrane switch that includes not only a normally open set of electrical contacts but also a normally closed set of electrical contacts. In one embodiment, a downward force applied to the switch pivots an elongated, flat rocker, to close the normally open contacts and simultaneously open the normally closed contacts. Pivoting of the rocker is yieldably resisted by an overlaying resilient membrane, which forceably returns the rocker to its original position when the force is removed. In another embodiment, a downward force applied to the switch lowers the center of a special disk into contact with an underlying circuit board, to close the normally open contacts, and simultaneously deforms the disk's periphery upwardly, to open the normally closed contacts. Internal stress in the deformed disk returns the disk to its original position when the force is removed. The rocker and disk are both retained without any special attachment in a specially-sized aperture formed in a spacer located between the underlying circuit board and overlaying membrane.

Abstract: The invention comprises an intrusion-detection system based on a switch 1 that provides more effective protection by means of an innovative arrangement of three intrusion-detection contacts 16-17-18 on an electronic circuit, connected to two different intrusion-detection electronic circuit and an intrusion-detection switch 1 with a special design that provides three different interconnections between said contacts in response to different intrusion attacks. The special arrangement of the contacts on the electronic board provides protection against different sophisticated attacks even without the participation of the intrusion-detection switch.

Abstract: A normally closed dome switch comprises a printed circuit board including a switch trace having first and second contact areas electrically insulated from one another, and a conductive switch dome having a central portion spaced from the printed circuit board and a plurality of contacting portions extending from the central portion such that each of the first and second contact areas is contacted by at least one of the contacting portions when the switch dome is unpressed such that the unpressed switch dome forms a closed switch between the first and second contact areas. The switch dome is resiliently pressable to urge the central portion toward the printed circuit board and pivot the contacting portions about a corresponding fulcrum to remove the plurality of contacting portions of the switch dome from contact with at least one of the first and second contact areas to open the switch.

Abstract: An improved keyboard is provided with a flexible metal cover, normally closed switches, and multiple throw switches. The metal cover is made flexible in the area of each key or switch by the provision of grooves in the metal surrounding each flexible portion. The normally closed and multiple throw switches include pellets which transmit the actuating force on a key or switch through a substrate on which a switch is mounted. The device may be configured in such a way that the pellet will push the normally closed contacts of a switch out of contact, or the pellet or pellets may mechanically link a stacked set of switches in order to provided ganged, multiple throw operation.

Abstract: A keyboard for a musical instrument having a plurality of elongated keys with each key having a rearwardly extending actuating arm. The arm has an upper and a lower nonresilient switch actuator for actuating a respective first and second keyboard switch with each switch having a substrate with at least one fixed contact. A deformable membrane has coupled thereto a movable contact which is adapted for movement into and out of electrical connection with the fixed contact. The first and second switches are positioned so that the lower actuator normally maintains closed the first switch and when the key is actuated the first switch opens and the upper actuator closes the second switch. The deformable membrane is formed of Poron cellular urethane which distributes and absorbs the actuation force and springs back to its undeformed shape when not actuated.

Abstract: A switch device structure includes an assembly of a main body and an operation body. An electrical connection module and an elastic unit are mounted on the main body. The contact arm of the electrical connection module has a first member and/or a second member with variable arrangement position. According to the position or motion of the operation body, the elastic unit provides an elastic force to push the contact arm of the electrical connection module into a contacting circuit closed state or make the elastic unit separate from the contact arm to form a circuit open state. The arrangement form of the first member and/or the second member of the contact arm of the electrical connection module is variable in accordance with the specification of the switch to achieve NO mode and NC mode.
