Automotive Battery Isolator Switches

Battery Isolation Switches provide a means of disconnection between :
Auxilliary battery bank power supplies
Electrical loads , for example; 12v & 24v DC Motors , Winches,
Automotive Battery charging circuits
12v or 24v Inverter
Engine generator / alternator

Automotive battery isolator switch circuit applications may include switching and isolation of battery banks on leisure and specialist vehicles.

The Battery Isolator switch has applications to prevent battery discharge caused by parasitic current drain where a vehicle may be standing for long periods of time.

A battery isolator switch can prevent unauthorised machine operation for example when construction plant is parked on a site or during mechanical maintenance.

Battery Isolation Device Location

It is recommended that battery isolator switches are

Located in a position providing safe access

Located as close to the power source batteries as practical

Not located where inadvert operation causes machines to stop or restart.

Labelling

Battery switch function should be labelled.

Terminal Insulation

Terminals should be insulated or protected to provide electrical separation.

Specification

Battery isolator switch gear specification should take account of maximum intermittent and continuous circuit (Amps) current at switch rated voltage.

Starter motors will demand a peak current draw as the engine is cranked from stationary to rotation especially in cold temperatures.

Misuse

Problems caused by misuse of a battery switch may occur when electronic components are present in the circuit eg if the battery switch is used to disconnect power when the engine is running , alternator diode damage may occur. Isolation of a power supply could cause a critical process to fail.

Battery Isolation Switches : Applications

On / Off control of main high current power supply to winches, power inverters, 12 volt or 24 volt motors.
Vehicle security to disconnect battery power supply preventing unauthorised startup.
Battery isolator switches used for emergency power shut off for Motorsports Road Race and Rally Vehicles (See MSA or FIA regs) should be accessible from both inside and outside of the vehicle and function to disconnect all electrical circuits and stop the engine.
Battery saving device where vehicle battery requires rapid disconnection and reconnection
Earth Moving Equipment anti vandal isolation.
Landrover 4x4 and Over land expedition vehicle battery isolation
Disconnection of leisure battery from towing vehicle
Agricultural machinery battery isolation
Groundcare machinery battery isolation
Marine yacht boat canal boat domestic or house auxilliary battery bank switching (see Boat Safety Scheme BSS guidelines).
Where a parasitic current drain exists a battery isolator switch may be used to disconnect the batteries from an unwanted load.

Important note : Vehicle computer control

Please check with manufacturers specifications and technical information as some vehicles may require computer software update after battery disconnection.
