1. TITLE OF THE INVENTION:

Compact Electromagnetic Push Switch Assembly

3. PREAMBLE TO THE DESCRIPTION:

The following specification particularly describes the invention and the manner in which it is to be performed: 4. DESCRIPTION:

Field of the invention:

[0001] The present disclosure generally relates to push switch systems, and in specific relates to the integration of electromagnetic coil in push switch that can be directly fixed to the panel without any extra items.

Background of the invention:

[0002] Now-a-days, manually operated electromechanical device with a plurality of sets of electrical contacts is the most familiar form of switches. Each set of electrical contacts exists in any one of the two states, one is the electrical contacts are touching each other thereby electricity will flow between them in this state. In other state, the electrical contacts are separated and thereby the electricity will not flow between them and the switch is in non conducting mode.

[0003] In general, electromagnetic switches are separately available in order to control motors and panels using relays, contactors, etc. However, they are not directly mounted to starter panel and electrical panels since it requires a relay base and channel.

[0004] In the current technology, an electromagnetic holding mechanism with push button actuating device and a switching device is used. By applying an actuating force, the push button assembly causes to depress the pushrod which engages to depress the plunger assembly. However, the cost and space required in order to make panel starters is high, and therefore, there exists a need to reduce the price and volume required to make the panel starters.

[0005] In the updated technology, an automatic power switching device is provided for household appliances such as heaters. It comprises of a push button, switch tongue, spring, bimetallic switch, and an electromagnetic coil. When the push button is pressed, the permanent magnet holds the switch tongue and supply power to the heater. The temperature rises at the heating element causing the bimetal switch tripped, then the electromagnetic coil is energized. However, the electromagnetic coil is not directly integrated thereby cannot hold the push button automatically.

[0006] Therefore, there exists a need to integrate an electromagnetic coil to push switch that can be directly fixed to the panel without any extra items. There exists a need to reduce the cost and space required in order to make electrical panels and starters and further provide automation in domestic and industrial automation areas. There exists a need to replace contactors and relays in pumps or motor controllers for tripping required items. There exists a need to replace lAmp to 40 Amprelays and provide a push switch that can be designed to operate with any required voltage and Amps with AC or DC supply.

[0009] Another objective of the invention is to replace contactors and relays in pumps or motor controllers for tripping required items.

[0010] Another objective of the invention is to replace relays with lAmp to 40 Amp and provide a push switch that can be designed to operate with any required voltage and Amps with AC or DC supply.

[0011] Yet another objective of the invention is to provide an electromagnetic push switch that can be used in domestic, industrial, agriculture, hospitals, home automation, inverters, electric control panels & startersetc.

[0012] Another objective of the invention is to provide an electromagnetic push switch which is durable, reliable, safe and maintenance-free.
