Manufacturers of switches and relays have faced several big challenges over the past few years. OEMs, particularly in higher-reliability markets, continue to look for greater flexibility and ...

When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

Standex Electronics has created a reed relay that measures 7.95 x 4.67 x 3.6mm and can switch 100V, 200mA, 3W or 8GHz. 8GHz is the -3dB frequency, at which the switch offers -5dB isolation when open. ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays use light to isolate the primary side, ...

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.
