Releco QR-C Relay C9-A41 DX, 24 VDC, Brand New Tested Surplus

You will find that the timer on this relay is pretty handy for intermittent tasks.

You will find that the AMP brand on this relay lines up with common panel layouts.

A nice touch is how the relay resists minor vibration, so bench tests stay predictable even when cables get moved around.

I like that it feels heavy-duty yet still offers remote access from my phone without any fuss.
