Relays and contactors are typically used as electrical interlocks. Say for example you have two relays, CR1 and CR2. You want to prevent CR1 from turning on if CR2 is on. You would wire the coil in series from CR1 into the normally closed contacts of CR2 to ensure that for CR1 to ener...
In an industrial setting, relay systems are used regularly. One very common example is when an electric motor needs to be turned on and off. Commonly called contactors and motor starters, they are a prime example of a relay system. We use a low voltage, low current circuit for our motor...
This is why, in most instances, it is not recommended when other motor starters with safety, such as automatic starters, are used. The automatic starters, which are made up of electromechanical relays and contactors, are used to turn the motor on and off. As current flows through the ...
aAuxiliary contactors shall be provided only where the circuit requirement cannot be met by the auxiliary switch arrangements and multiple contactors and relays will not be accepted in lieu of the auxiliary switches except as specifically approved by the Engineer. Auxiliary switches and contactors shall...
Power supply relays, starter relays, horn relays, fog lamp relays, wiper relays, and other types of relays are all common. The structure of the relay Iron core, coil, armature, return spring, contact, and other components make up an electromagnetic relay. The internal structure of a ...
The electromechanical motor controller is the more simple of the two groups and generally makes use of electromagnetic contactors or relays to stop, start, and reverse the motor's direction. In the case of three-phase star/delta starters, they can also be used to overcome high starting loads ...

Have a look at the power distribution switches, load drivers section on Digikey. There are many types, but often they're - N-Fet based (so high side with low rdson) - Gate boost driver built in so it can drive the nfet without you needing to supply higher voltages. ...
