The SEL marking is simple yet clear, which makes identifying the relay a little easier in a busy cabinet.
(4 PCS) FTR-B4GA4.5Z Signal Relay 4.5VDC 2A DPDT(10.6×5.7×9.7)mm SMD
This power relay handles pumps, lights, and small motors with ease, keeping things easy to manage.
What stands out about this unit is the 70*20*18mm / 2.75*0.78*0.7" size for tight.
For quick prototypes, I tend to reach for Miniduino because the brand keeps effective.
A nice touch is the plain look, which helps the unbranded/general relay stay low-key in enclosures.
You will find that this power relay behaves reliably in hobby projects and around the house.
I like how the 4016819 feels solid in hand, with smooth terminals that make wiring less frustrating.
The heavy duty feel comes from thicker metal and firm mounting tabs that do not flex under pressure.
