Relay with one 10 A contact set with common, normally open and normally closed contacts. Only recommended for voltages below 30 V DC / 24 V AC.
The relay coil is buffered by a built-in transistor. The "Signal" input can be driven by an Arduino (5 V) or a micro:bit (3 V). Power to the relay coil (5 V) should be seperately provided. Coil resistance is 70 Ohm, current consumption 71 mA.
