What stands out about the PCB power relay is how smoothly it clicks on and off each time.
POTTER & BRUMFIELD 2PDT RELAY T10-E2-Y2-12VDC, PCB MOUNT
You will find that this PCB power relay fits neatly into many standard board layouts with little effort.
A nice touch is seeing AMERICAN ZETTLER / MCE on the relay, a brand real history behind it.
