This technical primer breaks down defrost control board operation, key components, and practical troubleshooting steps every ...

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
