Review on ⏲ 12V 30A 5-Pin SPDT Time Delay Relay - 10 Seconds Delay by Patrick Pearson

The device worked fine, about 2 seconds. The NC pins only carry a few amps because the current flows in a thin trace on the board. I wanted to run glow plugs on a small diesel. Motor by switching off after 10 seconds via break contacts. The NO trace was built with more solder to allow for more current. I doubt it will handle 30 amps for very long though as the relay contacts are quite small. I cut the cover off the device and soldered the wire to the burned trace so I could use it to drive a REAL 30 amp relay. control glow plugs. I 3D printed the lid and glued it on to make it work for me, although it's not as advertised. The seller needs to clarify that it is only rated for 30 amps on normally open contacts and will not even connect normally closed contacts.
