Patent Number: 
Section: claims

1. An electro-technical device, comprising:a point source supplied with an input signal;a first portion electrically isolated from a second portion, the point source including an elongated element extending through and disposed within the first portion, the elongated element extending away from the first portion and toward the second portion; anda movable metallic film conductor fixedly connected to the first portion and being responsive to an electric field generated by the point source to move away from the point source and contact the second portion to complete a circuit and send out a control signal. 2. The electro-technical device according to claim 1, wherein the input signal is representative of one of a signal from a temperature sensor, a pressure sensor or a flow sensor. 3. A method of making an electro-technical device, comprising:forming a first housing portion;fixedly connecting a movable metallic film conductor to the first housing portion;inserting a point source including an elongated element extending through and into the first housing portion at a fixed location and spaced from the movable conductor, the elongated element extending away from the first portion, the point source being supplied with an input signal;providing a second housing portion opposite to and electrically isolated from the first housing portion, wherein the movable conductor is responsive to an electric field generated by the point source to move away from the point source and contact the second portion to complete a circuit and send out a control signal. 4. The method according to claim 3, wherein the input signal is representative of one of a signal from a temperature sensor, a pressure sensor or a flow sensor. 5. The method according to claim 3, wherein the first housing portion, the second housing portion and the movable conductor are made from metal by 3-D digital printing.
