ABSTRACT:
A method and structure for an electrical switch. According to the structure of the present invention, a liquid-filled chamber is housed within a solid material. A plurality of switch contacts within the liquid-filled chamber are coupled to the solid material, while a plurality of piezoelectric elements are coupled to a plurality of membranes. The plurality of membranes are coupled to the liquid-filled chamber. The plurality of switch contacts are coupled to a plurality of liquid metal globules. According to the method, a piezoelectric element is actuated, causing a membrane element to be deflected. The deflection of the membrane element increases pressure of actuator liquid and the increase in pressure of the actuator liquid breaks a liquid metal connection between a first contact and a second contact of the electrical switch.
