Works as described.

I use this to control the direction of rotation of a DC motor as shown in the diagram. I've attached a pinout that might be helpful to some people.

Pros
  • coil voltage: 5 V DC; Contact rating: 1A 125V AC/2A 30V DC; 2NO 2NC
Cons
  • Not bad but...

Good relays. Very important.

I have used several of these relays on some RF transceiver assemblies. They all worked perfectly. I have ordered three times and will most likely order more.

Pros
  • Compact and sealed design. Long lifetime. The relay can automatically regulate, protect and transform the circuit.
Cons
  • No Instructions

Good value for money, somewhat inconsistent performance

I keep ordering sets of these tiny Hui-Kes for low current projects (and blue songle relays for anything >1A). For both HK and Songles, there's always one in each pack that doesn't work as well as the others. Nothing changed this time: five of the six relays showed 25 mΩ (+/- 10%) on all contacts, and one measured 60-80 mΩ even after several open/close cycles. Interestingly, a contact that is always closed has a high resistance. All in all, even if one relay in the package performs less than

Pros
  • Product Name: PCB Power Relay; Model: HK19F
Cons
  • Obsolete model
