The VSS allows for two independent battery banks to be combined or isolated based on the presence of a charging source (such as an engine alternator or battery charger). Once the charging source is activated, the VSS lets the first battery of the main bank (engine battery) recharge; when this latter reaches 13.2V, the switch opens the circuit and lets the second battery (service battery) recharge. The emergency parallel function can be operated manually by means of a knob or through an On/ Off button on the dashboard. Recess or surface mounting.

Dimensions: 69x69x45 mm. \ 14.921.00 \ 14.921.02 Selecta New battery switch IP65 Allows using the batteries separately or together. Contacts in copper, springs in stainless steel, housing in PC / PTB / Fiberglass, flame-resistant. Cable protection end cap. Additional ring for flush mounting (hole Ø 95 mm). Specifications: UNI EN ISO 8846. A) MK II version. Selectable options: bank/battery "1", bank/battery "2" or both banks 1+2 simultaneously. Equipped with a device that automatically disconnects the alternator if the "OFF" function is activated without first shutting down the engines. Approval number: DIP006907SP. B) "MK III" version. Simultaneously connects, in position "1", the starting batteries with the engines and the service batteries with them, keeping the starting batteries separate and minimizing the risk of accidental discharge. In case of emergency, in position "2" the two circuits are connected together (in parallel). Approval number: DIP006907SP.
