Pico Circuit Diagram Elements

Contacts

Contacts are used to modify the flow of current in the circuit diagram. Contacts in the circuit diagram are either make or break contacts. Make contacts are open when off (de-energized) and closed when on. Break contacts are closed when off and open when on.

Contact	Pico Representation
Make contact; Open when off	I, Q, M, A, C, T, P, D, S, :, R
Break contact; Closed when off	I,
		Q, M, A, C, T, P, D, S, R

Pico works with different contacts, which can be used in any order in the contact fields of the circuit diagram.
