Hi there, I am working on a project where I need to switch an air bed pump ( http://goo.gl/IGBvR ) that draws 4500mA. I am using a 5V relay, that can switch up to 16A on 30VDC. Everything is working as it should, until I connect the motor. After about a minute, sometimes more, sometimes less, the re…

Relay becomes unresponsive after switching air bed pump
