Manufacturers of switches and relays focus on miniaturization while delivering greater functionality with more options.

If a mechanical relay turns on or off near the peak voltage when supplying AC, there is a sudden drop or rise in current. If you have an inductive load such as an electric motor, this can cause a ...

Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a ...

Protective relays and monitoring relays detect or monitor for abnormal power system conditions. Protective relays detect defective lines, defective apparatuses, or other power system conditions of an ...

Relays are still a good solution in some situations. When you’re dealing with high power, or when you need something exactly electrically identical to a closed switch, relays are a reasonable ...

Reach Power has developed wireless power relay nodes that extend the range and efficiency of wireless power transfer.

Omron Electronic Components Europe has launched a new high-power PCB relay, which needs up to 51% less mounting space than similar 480VAC 55A relays. Weighing just 18g, the relay needs 488mm2. The ...
