AUTO ELECTRICAL SWITCHES RANGE

CATALOGUE >> AUTOELECTRICAL SWITCHGEAR INDEX

We supply a wide range of switches for autoelectrical applications to UK purchasers

Product Group and page link
Battery Isolator Switch Range Battery main isolator switches are heavy duty switches capable of handling high peak currents found on automotive starter circuits or to switch auxilliary batteries. The Battery Isolator Switch may be wired to interrupt the battery positive supply lead or battery negative return lead .
Brake Light Switches Brake or Stop light switches are mostly of Normally Open type which contact the brake pedal so that when the pedal is depressed switch contacts close to apply power to either the brake light circuit, a relay , or complete a signal circuit.
Ignition Switches for Tractors and Construction Plant Lucas type ignition switches
Pin Switches for Courtesy Lights and Vehicle Alarm Systems
Push Pull Switch Range
Push Button Switch Range
Reverse Light Switches Range
Rocker Switch Range
Toggle Switch Range
3 Way Switch Range A three way switch is often used for direction indicator circuits where a common input can be switched to operate left or right flasher lamps On/Off/On

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.
