DPDT Relay DC 3V, 5V, 9V, 12V, 24V Coil 8 Pin Mini Relay
HK19F
- 8 Pin, 1A 125VAC/2A 30VDC
- Low power consumption and quiet operation.
- Driven by an Arduino I/O pin to turn a DC-AC inverter on and off
- Handy for any circuit needing a relay w/ low current consumption
- Package Content:
- 12 x Pcb Power Relay
HK19F Relay, Arduino driven DPDT
- These mini relays fit into a standard IC socket so ou dont need a special socket.
- These dpdt relays fit the breadboard and work for the Make Electronics book by Charles Platt.
Good Sealing
The waterproof is much better than others with only glue bonding.
The clearances between the casing and the contacts is almost nill, so the casing pushed in enough to permanently push the contacts together.
Safe and Durable
These little relays fit the breadboard and electronics
Epoxy sealed could be more rugged, perfect for your application style (inside a control box)

I'm using this to switch outdoor lights so I wanted to use a latching relay. I have an Arduino that sends a 100 ms pulse to turn it on or off. Diodes are needed to prevent flyback current when switching.

Used this in a microcontroller project. The measured coil resistance is about 130-ohms.

Liked the price. Used for a model railroad layout.

I'm using these in pairs, in an automotive application where I needed a latching 2A relay. Compact and quiet, these are working perfect for my application.

These are great little relays, that fit very nicely right on a breadboard, or on a protoboard. I tested two each of the 5V and 12V relays, to characterize them for my own projects. I didn’t test them all, because it’s time consuming, and two samples gives a reasonable ballpark estimate of real performance.For the 5V relays (coil resistance ~ 127 ohm):Relay 1: Pull-in @ 2.8V, 20mA – Drop-out @ 1.1V, 7mARelay 2: Pull-in @ 3.1V, 23mA -- Drop-out @ 1.15V, 8mAFor the 12V relays (coil resistance ~736 ohm):Relay 1: Pull-in @ 8.3V, 10mA – Drop-out @ 3.1V, 3mARelay 2: Pull-in @ 7.1V, 9mA -- Drop-out @ 2.5V, 3mAAs you can see, these pull in at more like 60% of the rated voltage, and drop out at about 20% of the rated voltage, rather than the 80% and 10% listed in the spec sheet. When operating at exactly 5V or 12V, the current is very close to the spec value, and the coil resistances are within spec. Really, it’s only the pull-in and drop-outs that are not. However, this is not super problematic for me, since I tend to control these relays with digital signals, so I am either running full voltage, or zero voltage. You only need to take these specific pull-in or drop-outs into account when you’re doing semi-precise RLC analog timing. I didn’t test the max contact current, because I don’t want to test to destruction.Note, because the 5V relay pulls in at about 20 mA, you should be able to use these (maybe with some caution) directly with an Arduino microcontroller, which can source a max of 40mA, but only 20mA sustained, and only a max of 200mA from all pins combined. You should NOT drive them directly with a Raspberry Pi, as the Pi GPIO can only source 3 mA before burning out.Even though the pull-in and drop-out currents are not within spec, I’m still going to give these 5 stars because they will still work perfectly for me, and at about $1/relay, the price is reasonable.

Limited ac uses and pins are very fragile. Must use a circuit board.
