## Abstract

The various embodiments of the present invention provide an automatic vibrational electrical switch device that includes a shell, a first sphere, a transient sphere and a pressure switch. The pressing operation of the transient sphere towards an upward direction results in placing the first sphere load over pressure switch to keep the electric switch in a normal mode and when any vibration occurs in a normal mode the first sphere load is released and the electric switch is automatically operated in a quake mode.

## Claims

### Claim 1

A vibrational electrical switch device comprising: a shell; a first sphere; a transient; and a pressure switch;
wherein the first sphere, the transient and the pressure switch are located inside the shell, wherein the pressure switch comprises a pressure bar, a spring placed underneath the pressure bar and biasing the pressure bar in an upward direction; a metal blade connected to a lower end of the pressure bar, and a plurality of connection bars, wherein the metal blade provides an electrical connection between at least two of the pressure bars,
wherein the pressure switch is operated in a normal mode and in a quake mode;
wherein a pressing operation of the transient from an initial resting position towards the upward direction results in placing the first sphere over the pressure bar of the pressure switch so that the pressure switch operates in a normal mode;
wherein the transient returns to the initial resting position so that the first sphere seats over the pressure bar and is solely supported by the pressure switch and when a vibration occurs during the normal mode of operation, the first sphere is released from the pressure bar and the pressure switch is automatically turned to a quake mode.

### Claim 2 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the shell comprises: a board to hold a plurality of internal components; and a lid arranged above the board to enclose the internal components.

### Claim 3 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the first sphere is a weight to protect the pressure switch in the normal mode and for connecting electric current during the normal mode.

### Claim 4 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the transient is designed in such a way to place the first sphere over the pressure bar of the pressure switch.

### Claim 5 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein an end section of the pressure bar over which the first sphere is placed is a vibrating section.

### Claim 6 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the pressure bar is adapted to flip the metal blade in an upward direction and a downward direction to change a direction of flow of electricity.

### Claim 7 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the metal blade performs the action of disconnecting and connecting an electrical power supply.

### Claim 8 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the spring is adapted to activate the pressure bar automatically and dynamically.

### Claim 9 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the plurality of electrical connection bars include at least four connection bars for an input and an output of an electrical power.

### Claim 10 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein a vibration rate of the pressure bar during the quake mode depends on a diameter of the pressure bar in the pressure switch.

### Claim 11 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the pressure switch divides the electric current to perform at least one of the normal mode operation and the quake mode operation.

### Claim 12 (depends on 1)

The vibrational electrical switch device according to claim 1, wherein the vibration during the normal mode results in a change of flow of electric current to one or more devices.
