I'm considering to use the Omron G5V-1 Relay in order manage a 5 VDC 1.5 A charge. Reading the datasheet I did not completly understood what is the Relay maximum supported current, considering that I'm working at 5 VDC.
What's the difference between Rated Carry Current and Max Switching Current? Which of these two should I consider as the current limit?
In the last page of the datasheet I found this paragraph:
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continuously for long periods (without switching) can lead to unstable contacts, because the heat generated by the coil itself will affect the insulation, causing a film to develop on the contact surfaces. Be sure to use a fail-safe circuit design that provides protection against contact failure or coil burnout.
What Long-term means? Are we talking about hours, days or what?
