Abstract
A marine electrical system may include a first electrical subsystem and a second electrical subsystem. A jumper switching device may be interposed between the first and second subsystem. The jumper switching device may have normally open contacts. The first electrical subsystem may remain electrically independent from the second electrical subsystem except when the normally open contacts of the jumper switching device are closed.
Claims10
A marine electrical system comprising:
- a first electrical subsystem;
- a second electrical subsystem;
- and
- a jumper switching device interposed between the first and second subsystem, the jumper switching device having normally open contacts;
- the first electrical subsystem being electrically independent from the second electrical subsystem except when the normally open contacts of the jumper switching device are closed.
2 more elements
A jumper switching device comprising:
- two spring-biased solenoid relays having normally open contacts;
- first and second positive battery-terminal cables interconnected with first and second contacts of a first one of the solenoid relays;
- first and second negative battery-terminal cables interconnected with first and second contacts of a second one of the solenoid relays;
- a switch interconnected between the first positive battery-terminal cable and coil of the solenoid relays at coil terminals;
- and
- an electrical connection path from said coil terminals, through said coils to the first negative battery-terminal cable.
