It is a way to isolate a circuit from the rest of the circuits in a system. If work or maintenance has to be preformed on a certain piece of equipment a switch is used to de-energise the equipment.
If they were in series in the circuit, they would act as on/off switches.
What are Air Force types of ied switches
One of the switches is bad most likely. Replace.
Most circuits require a load.
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
paralel circuits
The most common application of tri-state logic is in the use of LED circuits. They can also be used on a shared electric bus.
Most of the circuits are contained within your computer.
Ammeters are added in series to the circuit to be monitored.
Two different switches. The combination switch on the column is most likely the culprit. This may be fuses. The turn signals and hazard lights are fed by separate circuits.
While many of the terminal parts of a circuit may be a series element, in most circuits there will be both series and parallel components. Neither is superior - they both have their appropriate applications.
By far the easiest and most cost effective way to do this is to find a scrap Golf of the same year fitted with electric windows you will then be able to remove all the parts that you need to convert yours I:E wiring loom relays switches window motors.
