DESC:FIELD OF INVENTION:
[001] The present invention relates to switches. More particularly, the present invention relates to a single isolating switch system for switching ON/OFF all heat generating devices inside galleys.

BACKGROUND AND PRIOR ART:
[002] A galley is a food preparation area on an aircraft, a train, or a ship, As such, the safety of the galley is of utmost importance, particularly in ships, since there are many heat-generating equipments, and the possibility of fire due to heat is very high. In case of fire, there is a need to switch ‘OFF’ the power supply to all equipment, in order to control the fire from spreading and to avoid damage.

[003] There are many heat-generating equipments inside the galley such as a frying pan, electric induction range, and other equipment like a rice boiler, water boiler, etc. Apart from this, there are many high loads inside the galley. These loads are categorized into 415 VAC and 230 VAC loads. Also, these equipments need to be isolated during non-working hours when the galley is locked. In addition, there are some loads like refrigerators and other cooling devices that shall remain ‘ON’ during non-working hours.

[004] Conventional isolating switches have very limited capability, wherein it can switch ON/OFF only some of the 380V/415VAC galley loads. As such, the problem persists where other equipment does not have the facility to be switched ON/OFF during non-working hours. Further, during the said non-working hours, some equipment like refrigerators and other cooling devices needs to be switched ‘ON’ due to its requirement.

[005] Therefore, a galley isolating switch is required to immediately switch OFF the power supply to all the equipment in a single operation.

[006] Thus, there is a need for a galley isolation switch, which can switch ‘OFF’ the 415VAC and 230VAC, except for cooling devices like refrigerators, etc.

SUMMARY OF THE INVENTION:
[007] The primary object of the present invention is to provide a galley isolation switch system that can switch ‘ON/OFF’, 415VAC, 230VAC, and combined 415VAC/230VAC with the exception of cooling devices like refrigerators, etc.

[008] Another object of the present invention is to provide a galley isolation switch circuit system capable of performing ON/OFF operations for 230VAC galley loads, 415VAC galley loads, and both 415VAC/230VAC galley loads utilizing the contactor circuit.

[009] An aspect of the present invention pertains to an isolation switch system for galley safety. The isolation switch system comprises a power panel configured to supply electric power to galley loads through a local control box, a plurality of single isolation switch panels, wherein each single isolation switch panel is configured to independently switch ON/OFF the respective galley loads, a local indication panel configured to indicate the status of galley loads, a remote indication panel configured to remotely monitor the status of galley loads.

[010] In an aspect, the contactor circuit panel is configured to control the electrical power supply to galley loads.

[011] In an aspect, the plurality of single isolating switch panels specifically controls the 230VAC, 415VAC, and combined 415VAC/230VAC galley loads using the contactor circuit panel.

[012] In an aspect, the 415VAC loads can be operated through the single isolation switch panel positioned on the local control box.
