                    CTA-ID : 2014524

                    Customer asks how does the CA2SKE20 alternating relay operate?

                    Issue:
                    Operation of the CA2SKE20 alternating relay's contacts.

                    Product Line:
                    Alternating Relays

                    Environment:
                    TeSys SK IEC Style Relays

                    Cause:
                    Verify if the CA2SKE20 relay will work for the customer's application.

                    Resolution:
                    The relay has 2 normally open contacts. When the alternating relay is energized only one of the contacts closes. When it de energizes this contact opens. The next time it energizes and de energizes, it alternates which contact it operates.
