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 ...

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 ...

Figure 1. Restructuring the circuit in Figure 2 with redundant machinery power contactors and a double-pole interlock switch increases the probability that the circuit will work, even if a single ...

Sensata Technologies (NYSE: ST) today announced the launch of its STEV high-voltage contactor series, engineered for high ...

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.

The STEV high-voltage contactor series from Sensata Technologies is designed for battery electric and plug-in hybrid vehicle ...

Relays, Contactors, and Motor Starters provides an overview of the primary components involved in electric motor control. Relays are electrical switches that control a circuit. When activated by ...

A simple circuit includes a safety interlock switch and a machinery power contactor. Either device can experience a fault, such as a sticking or welded contact. A short circuit also can occur. In each ...
