The JR-1086 is a medium-sized relay manufactured by MEC that is used in many applications such as high power switching, heating, cooling, and automotive applications. It features a maximum switching capacity of 250VAC/2A, a current load rating of 10A, and an operating temperature range of -40°C to 125°C. The relay has three main components: a coil, an armature, and a set of switching contacts. The coil produces a magnetic field which attracts the armature when energized, thus completing a connection between the switching contacts. The relay can be controlled either mechanically, using an external switch, or electronically, using a voltage.
