Fitting Guidelines for Automotive switches

We supply a wide range of autoelectrical switches for 12 volt and 24 volt motor vehicle applications.
The optimum switch for your application may be selected based on voltage and current handling specification.
Switch location and ergonomics must also be taken into account.

Multiple auto electrical switches may be used to manufacture automotive electrical switch panels during project builds.

If planning to drill holes in vehicle interior or exterior panels always check what is the other side of the panel before you drill to avoid damage to wiring looms and other components.

Parts and tools you may require

  • Electric drill , Air drill or Portable battery drill
  • Step drill , Cone drill or suitably sized drill bits
  • Wire cutter
  • Cable insulation stripper
  • Pre insulated terminals
  • Terminal Crimp Tool
  • Rubber grommets
  • Electrical cable.

We supply a full range of auto electrical wiring accessories and tools for use in the manufacture, installation, repair, refurbishment of specialist vehicle electrical systems

Classic Vehicle Switch Circuits

On older vehicles the switch is often in the 'live' side of the circuit to the component. DC systems often use chassis ground as the circuit return.

Modern vehicles fitted with electronic control modules

Modern vehicles may have switches fitted in the live side of the component circuit,
or where a control module is fitted the switch may trigger a signal path from control module to ground.

Voltage drop across switch contacts

An excessive voltage drop across switch contacts may indicate that the switch is faulty due to worn or dirty contacts creating high resistance requiring switch replacement.
