Magnetic Contactor
used to control the operation of an electric current a large relay usually, usually, used to switch current to an electric current motor or other high power load a device uses small control current to energize or de-energize a load. It can handle high amounts of current and also combined w overload relays to create motor starters
electrically controlled switch used for switching a power circuit, similar to relay r elay except with higher 12/23/2012 amperage ratings. 3
Motor controls contains Control Circuit
A circuit contains the control device that will initiate starting or stopping the motor, motor, by the means of the start/stop push button.
Control circuit provides a temporary path for energizing he coil and permanent path through the contact
Delays energization of the coil preselected time to allow switch contact bounce to cease.
