Bestact can do it up to about 50VA directly and is the most suitable for valve switches such as AC solenoids. It means that Bestact can perform functions of both conventional reed switches and mechanical power relays. But that is not all.

By using a single Bestact, the reliability rises significantly; circuit wering becomes simpler eliminating the need of contact protection circuitry or interposing relays.

Because of the dual contact structure and the wiping effect, it provides excellent reliability for both analog circuits and dry circuits. According to our field failure data, reliability is significantly better than both mercury relays and semiconductor relays. (Bestact: 4.8FIT, Solid State Relays: 80-90, Mercury Relays: 50-60)

It can be used in circuits from 1V 1mA up to about 240CAC 5A (inductive load), which makes it ideals as the ouptut contact for controllers. There is no need to worry about load voltage or current levels.
