What does the brake light switch do?

The brake light switch is usually a simple on/off switch that completes the electrical circuit to the lamps that is activated by the brake pedal.

How does a brake light switch work and what are the components?

When the brake pedal is in the up position, the brake light switch will be off, just like a lamp switch in the house. When the brake pedal is pressed down, this releases the plunger in the switch and the contacts meet to complete the electric circuit to the brake lights.

In some vehicles it is a simple push in and twist plunger switch but in other it can be more complex than that. There are no serviceable elements in a brake light switch, so if one becomes faulty, it is simply replaced.

Typical symptoms that require a brake light switch to be replaced.

• When none of the brake lights work and the fuses and bulbs have been checked.
• The brake lights remain on, even without the pedal being depressed.
• If one brake light works though, no matter how many others do not, it is not the brake light switch at fault.

What happens during a brake light switch replacement?

Changing brake light switches is a routine repair for all mechanics and can be done both kerbside as well as in the workshop, providing it is safe to do so.

The mechanic will;

• Inspect the brake light system and corresponding switch.

FAQ’s

Can I supply my own parts?

No, we will not fit customer supplied parts unless they are a brand new item, purchased from a dealership with the receipt as proof of purchase. There is no flexibility over this due to insurance and warranty issues.

What happens if the mechanic finds that the brake light switch doesn’t require changing and the problem is due to another issue?

In this scenario, the mechanic will provide a no obligation quote for the correct repair. Should you accept this, the mechanic can alter the booking accordingly. If you decide not to go ahead with the alternative repair, the mechanic can change the booking to a call out and diagnostic booking and charge according to the time spent with the vehicle and call out.
