Abstract:
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.
