Electronic pressure switches for brake lights

Brake lights serve an important function as they warn the driver behind that your vehicle is slowing down. Off-road vehicles driving on public roads must be equipped with a brake light system according to the road rules.

Although many brake light systems are commonly solved by using a mechanical switch, Danfoss recommends using an electronic switch.

Problems with mechanical switches

  • Mechanical switches often leak causing warranty claims 
  • The electrical contacts can burn out resulting in failure 
  • The general accuracy is around +/- 5% 
  • The set point can drift over time 
  • Over and burst pressure limitation due to moving parts

Features and benefits

Electronic pressure switches have 100% welded construction so no leakage possible

No electrical contacts to burn out

No set point drift

Over and burst pressure advantage due to fully welded design

All the advantages from the "world" of transmitters in relation to vibration shock etc.

A more reliable brake system

Less wear outs of the switch due to no mechanical parts

Reduced warranty claims
