Question 1A very common form of latch circuit is the simple "start-stop" relay circuit used for motor controls,whereby a pair of momentary-contact pushbutton switches control the operation of an electric motor. Inthis particular case, I show a low-voltage control circuit and a 3-phase, higher voltage motor:lllllllllTo 3-phasepower sourceF1F2L1StartStopM1M1M1motorExplain the operation of this circuit, from the time the "Start" switch is actuated to the time the "Stop"switch is actuated. The normally-open M1 contact shown in the low-voltage control circuit is commonlycalled a seal-in contact. Explain what this contact does, and why it might be called a "seal-in" contact.
