Electrical contactors are devices used to switch electrical circuits on and off. They are designed to handle high current loads and are typically used in applications where frequent switching is ...

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.

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 ...

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Munich – Schaltbau, located in Munich, has launched a new safety contactor designed for use with control boxes. It combines the functions of the main contactor and the disconnecting and earthing ...

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 ...
