AC Motor Control Circuits Worksheet - AC Electric Circuits
Notes: This circuit is known as a latching circuit, because it “latches” in the “on” state after a momentary action. The contact in parallel with the “Run” switch is often referred to as a seal-in contact, because it “seals” the momentary condition of the Run switch closure after that switch is de-actuated. The follow-up question of how we may make the motor stop running is a
