Manual key switch

Onboard systems usually consist of two or more batteries that function independently when powering the 12, 24 or 48 V consumers. These batteries require independent charging with reliable battery isolators and other peripheral equipment. 

Mastervolt offers several intelligent solutions:

  • Battery isolators that divide your charge current with a minimum energy loss.
  • The Charge Mate for connecting and/or disconnecting two batteries.
  • Robust manual switches for centrally turning off the power of the onboard network or starter circuit.
  • Battery Watch for monitoring the condition of your batteries (also usable as main switch).
 

Mastervolt supplies high current battery switches that can be used for switching off the battery negative pole or to distribute the charge current over several batteries manually. In this way the batteries are charged one by one under your guidance.

This maintenance free manual switch, made of polycarbonate material with heavy duty metal contacts, has on/off positions to be chosen with a key. Designed for built-in or surfaced mounting, the switch is spark proof according to SAE guidelines. Therefore it can safely be used in vessels with petrol engines.

But simply using a battery switch does not guarantee batteries cannot become discharged at the same time. Much better results can be achieved by placing a battery isolator between the source and batteries. The three or more diodes mounted inside isolate the charge current and prevent it from re-circulating.
