- The relays have 5 pins, can automatically adjust, protect and transform the circuit.
- Widely used in the remote control, communication, automatic control system, electronic equipments, etc.
- It can control small motors, incandescent lamps, indicator lights, low-power power supplies, intelligent instrumentation and various solenoid valves, etc. It can also be used as a pusher for high-power electromagnetic contactors.

広く使われている 5ピン出ている リレーです。背面に配線の絵はありません。欲しいですね。どちらが NO or NC なのかは テストしてからでないと使えません。 5V と少し低めの電圧で動作します。安定化電源でテストすると 3Vぐらいでもなんとか動作する感じです。ちょっと不安定になるかもしれませんが、乾電池2本で辛うじて 動作させることはできるでしょう。

Works, at least the one I've tried, but be aware that these don't fit any PCB or breadboard I've tried. You'll have to solder or clip wires to the pins. Kind of annoying considering the name has PCB in it. You'll have to be creative if you plan to use these in a permanent project.

The "Weasch 6Pcs PCB Power Relay JQC-3F(T73), DC 5V Coil, 7A 240VAC, SPDT, 5 Pins (6)" I received exceeded my expectations.For busget relays, the coil draws a nominally low amount of current (tested to less than 50ma at 5vdc). Contacts click solid and bounce was measured to be low for a budget relay.I have no issues with these relays. They work well and are a great alternative for DIY, hobby or prototyping circuits.
