Answer / doli tomar
When a relay is used to switch a large amount of electrical
power through its contacts, it is designated by a special
name: contactor. Contactors typically have multiple
contacts, and those contacts are usually (but not always)
normally-open, so that power to the load is shut off when
the coil is de-energized. Perhaps the most common
industrial use for contactors is the control of electric
motors.
