Body Switches & Relays: What Experts Say

Just like any machine, the car has components that transfer energy between two points. This energy can be controlled by using a button. In the vehicle, these components are called switches, relays, and sensors. When these parts break or wear, electricity transmission and vital sensors stop working. The type of relay most frequently used in the automotive industry is the small cube-shaped unit known as a standard relay or a mini relay. Relays, in general, are used to enable a low amperage circuit to switch on or off a higher amperage circuit. Relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals.

Read below to know the types of car body switches & relays:

When you operate any function inside the car, you are using a switch in some fashion. There are rocker switches, push buttons, ignition switch, starter switch, lever switches, toggle switches, switches for accessories like radio, interior lights, buttons used for air cooler, power windows, and many more in different styles. All have different appearances, and while some operate in the same way, switches are used for different functions. 

The type of relay most frequently used in the automotive industry is the small cube-shaped unit known as a standard relay or a mini relay. Other types of relays are Changeover Relays, Normally Open relays, Potted relays, Flasher relays, Thermal (Standard) Flasher relays, Electro-Mechanical Flasher relays, LED Flashers relays, Wig-Wag Flashers relays.

Here are the important features of car body switches & relays:

• Switches are strong, light, and low-friction. Plastic is a perfect material for the job. 
• Low friction plastics can be used in switches. 
• Using plastic means these switches require less maintenance than metal, there are places where metal can’t take the heat. 
• Switches that are made from high-performance plastics can withstand high temperatures and resist corrosion. 
• Relays are switches that open and close circuits electro mechanically or electronically. 
• Relays control electrical circuits by opening and closing a contact point. 
• Relays control the current supplied to a particular component of your vehicle and are very sensitive to small electric currents. Although relays are sensitive to smaller currents, they can be used to drive components that need larger currents.

Have a look at the working of car body switches & relays:

Just like any machine, the car has components that transfer energy between two points. In the vehicle, these components are called switches. All have different appearances and while some operate in the same way, a switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices, either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks, and the power flow is interrupted. 

A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. The heart of a relay is an electromagnet, a coil of wire that becomes a temporary magnet when electricity flows through it. When power flows through the circuit, it activates the electromagnet, due to which, a temporary magnetic field is generated, and that attracts a contact point and activates the system. When the power is switched off, a spring pulls the contact point back up to its original position, switching the circuit off again.

Willing to know common car body switches & relays problems? In that case, you have arrived at the right location. Keep on reading further.

1. Ignition isn't working

The major function of the automobile body switches and relays is to provide power to all control modules and sensors required for the engine to work. If nothing happens when you turn the key in the ignition lock and you know the car battery is charged, there's a good chance something is wrong with the car body switches and relays. These problems must be addressed as soon as feasible. You will be forced to travel without your car if this does not happen.

2. Ignition power might fluctuate

There could be a problem with the body switches and relays if your dashboard blinks like a table-flipping game. When rust develops inside the car's body switches and relays, problems arise. The connecting space inside the relay may become too narrow as a result, causing the ignition to shut off and on extremely quickly.

3. Car battery dies

When you turn off the ignition key, the ignition relay should turn off power to all engine components as well; otherwise, the car battery would be drained. When the ignition relay fails, the ignition system may remain on even after the keys have been withdrawn from the ignition. After you remove the key, the circuit will not open, and the battery will discharge.

Therefore, if you're staring at a battery that died, which was working fine till the day before, the car body switches and relays could be to blame.

4. Engine stalls issues

The automobile body switches and relays provide power to important engine components, such as the fuel pump and ignition coils. Your engine will die quickly if these components are missing, so you can probably anticipate what will happen if it can't deliver electricity to them. The body switches and relays may be at blame if your automobile shuts off while you're driving.

5 Electronics have a foul odour

In electronics, a poor connection generates heat. An automobile body switch or relay that has corrosion, rust, or water inside of it might develop a faulty connection, resulting in a lot of heat. As a result, the plastic cover over the relay will melt. If you've ever smelled a burnt electronic stench, the next time you get a whiff of it, examine the car body switches and relays.
