- 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.

There relays they worked as expected made a little project on a bread board and ran them on off every 90 seconds for 3 days they worked fine.

Images show a test w/ one of these - function generator is sending a square wave at 1hz with 50% duty. Function generator's signal goes through a resistor to the collector of a 2n3904. E-C sinks the relay to ground, PSU is providing 3vdc. Coil consumes about 120mA when on. Bench meter is measuring continuity through the NO contact.

I tested each of 6 received, and with 3V to the coils, response was immediate and repeatable. Exceeded expectations for consistency at this price point, will update with any unexpected results in further testing. 5 stars on initial impressions.
