Each additional start button should be connected in parallel with the first start button, and all additional stop buttons should be connected in series with the original stop button. Figure 1 shows examples of the additional start and stop push buttons in a three- wire circuit.
Moreover, Why the normally hold in contact is connected in parallel with the start button?
The purpose of the hold in contact is to provide a current path through the relay coil when you release the start button. That is why it is wired in parallel with the start. Similarly, the stop is wired in series to break the relay circuit and hence stop the motor.
Secondly, How do you wire an open Close stop switch?
Connect each open button (opposite of the common side) to the open terminal of the operator. Connect each close button (opposite of the common side) to the close terminal of the operator. Connect the common side of one of the 3-button control stations to the common terminal of the operator.
Simply so, How do you wire a push button starter switch?
What is the first action when the start button of a three wire control circuit is pushed?
When the start push button is depressed, voltage will flow through its contacts to energize the motor starter coil.

Why is a two wire control unsafe to be used in a motor control circuit?
Two-wire control devices won’t carry sufficient current to operate large motors. In addition, 230-volt motors and three-phase motors require more contacts than the one contact usually provided on two-wire devices. Two-wire controls may be connected to operating coils of magnetic switches, as shown in ill.
