likströmväxlar
Likströmväxlar, often translated as direct current relays or DC relays, are a type of electrical switch that uses a direct current (DC) coil to control the opening or closing of contacts. Unlike alternating current (AC) relays, which are designed to operate with AC power, DC relays are specifically engineered for DC circuits. This distinction is crucial because the electromagnetic principles governing their operation differ between AC and DC.
The fundamental design of a DC relay typically involves a coil of wire wrapped around an iron
DC relays are widely used in various applications where direct current is prevalent. This includes automotive
