Battery Isolation Switches provide a means of  disconnection and reconnection of battery banks. Battery isolator switch gear should be specified to take account of  maximum intermittent and continuous circuit (Amps) current at switch rated voltage. Auto electrical system peak current will usually occur as a vehicle engine is started from cold as the starter motor rotates, though battery isolator switches may be used on other circuit applications for example to switch in extra battery banks on leisure and specialist vehicles  eg where an inverter power system is in use or to switch main power supply to DC winch motors. The Battery Isolator switch also has applications to prevent battery discharge from parasitic current drain where a vehicle may be standing for long periods of time. A battery isolator switch can also prevent unauthorised machine operation for example when construction plant is parked on a site.  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.

Battery Isolation Switches : Typical Main 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
  • Emergency power shut off for Motorsports Road Race and Rally Vehicles.
  • 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
  • Agricultural machinery battery isolation
  • Ground care machinery battery isolation
  • Marine yacht boat canal boat domestic or house auxilliary battery bank switching
  • Where a parasitic current drain exists a battery isolator switch may be used to disconnect the batteries Important note : Please check with manufacturers specifications and technical information as some vehicles may require computer software update after battery disconnection.
