Abstract
An electro-technical device includes a first housing portion electrically isolated from a second housing portion with a point source being disposed within the first housing portion. A movable conductor is connected to the first portion and is responsive to an electric field generated by the point source to cause the movable conductor to contact the second housing portion to complete a circuit and send out a control signal.
Claims5
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;
- and
- a 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.

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.
