This Application is based on and derives the benefit of Indian Provisional Application 202111051616 filed on 10/11/2021, the contents of which are incorporated herein by reference.
TECHNICAL FIELD
[001] The embodiments herein generally relate to starting systems in vehicles and more, particularly to a starter switch having a separate circuit/contact line for an ignition coil, and a separate circuit/contact line for vehicle loads, a starter motor, a battery, and a regulator rectifier and charging coil (alternator).
BACKGROUND
[002] Vehicles are operated through a starter switch. The starter switch may also be called as ignition starter switch or ignition switch. The ignition starter switch or ignition switch is used for turning on and turning off power supply to the electrical system of the vehicle and for starting/cranking an engine. The ignition starter switch achieves the functionality of turning on and turning off the electrical system and engine by altering the electric supply to the various components of the vehicle using switching effect. The ignition starter switch used in such heavy vehicles operates in three positions: OFF, auxiliary and ON/ignition. When the ignition switch is in the OFF position, the engine as well as the electrical system of the vehicles is off. When the ignition switch is turned to auxiliary position, power is supplied to the electrical system and the electrical system turns on. When the ignition switch is turned to ignition, cranking of the engine takes place and the engine starts functioning. Once the cranking is done, the ignition switch returns to auxiliary position. Conventional ignition starter switch includes a single ignition switch circuit, a battery switch circuit, a vehicle load circuit and a starter motor switch circuit. There may be a possibility of ignition coil burn/ short circuit

as since the aforementioned switch circuits are connected (closed position) when the starter switch is in the ON position. Providing a separate circuit/contact line for ignition coil, and a separate circuit/contact line for vehicle load, a starter motor, a battery, and a regulator rectifier and charging coil (alternator), is difficult and is one of the challenges posed to the original equipment manufacturer (OEM).

[004] Another object of embodiments herein is to provide the starter switch with separate circuit/contact line for an ignition coil, and a separate circuit/contact line for vehicle loads, a starter motor, a battery, and a regulator rectifier and charging coil (alternator).
[005] Another object of embodiments herein is to provide the starter switch with two ignition switch circuits, a battery switch circuit, a vehicle load switch circuit and a starter motor switch circuit.
[006] Another object of embodiments herein is to provide the starter switch in which a first ignition switch circuit and a second ignition switch circuit are connected in series, and a battery switch circuit, a vehicle load switch circuit and a starter motor switch circuit are connected in series.
[007] Another object of embodiments herein is to provide the starter switch which eliminates the possibility of ignition coil burn/ short circuit.
