The device is shown in its simple form in the drawing below. Two thin wires ww made of soft iron or steel with platinum contact ends cc are attached to a small glass tube s. Coil S wound with wire surrounds pipe t. The contact points are of such a shape that the wires can be bent sufficiently without the separation being too large. When the current passes through the coil S, the wires ww are separated and the distance between the contact ends will increase. The tube is moderately emptied.
The dielectric between the ends is strained as with sensitive powders, very close to breakdown, with the help of the battery and when the signal enters the circuit the dielectric relaxes under the increased voltage so that the current from the battery passes through the coil S, separating the ends and thus breaking the battery circuit.
In this case, a series connection of the contact ends cc, coil S and battery is assumed, but the connection can be achieved in several other ways in order to achieve the same result – i.e. automatic interruption of the current after receiving the signal. The contact ends must be very close to each other and pointed.
Spacers ppp exist to limit the movement of wires ww and prevent vibration after each activation. It can be placed on S and an additional coil in order to adjust the wire so that their ends are at the necessary small distance, which is easily achieved by adjusting the current through the additional coil, and for registering the signal, one independent relay can be connected to the circuit in an adjustable way .
The degree of vacuum can be made variable. In the first device, coil S had 24 layers with 94 turns in each layer, or a total of 2256 turns of wire No. 21. The resistance was 14.7 ohms. With W
