Deadman or failsafe switches. Think of them as an and gate logic circuit...all switches must be on (1) in order to power the load (1).
The output of an AND gate is set only when all of its inputs are set, and when switches are wired together in series, current can flow only when all of the switches are on.
Switches used in electrical circuits are wired in series with either a parallel or series load. In parallel loads, the switch is upstream from the parallel circuit, so that the switch will shut off all of the parallel circuits.
Normally putting the batteries in series would have more effect.
A parallel circuit
Normally I would expect the elements to be wired in parallel so that the loss of one element does not cause the others not to work. It is possible for some manufacturers to wire a pair of elements in series so that they could use say 110v elements as standard so that they can be utilized on 230v toasters as well.
They are wired in parallel, series and series - parallel.
The output of an AND gate is set only when all of its inputs are set, and when switches are wired together in series, current can flow only when all of the switches are on.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
In control circuit wiring the safety switch is in series with the holding coil.
When DC voltage sources are wired in series they become additive.
No.
Yes.
The duration of Wired - TV series - is 3600.0 seconds.
A stop switch is wired in series with the power supply and the load.
