Bestact can perform functions of both conventioal reed switches and mechanical power relays.

But that is not all. By using a single Bestact, the reliability rises significantly; circuit wiring becomes simpler eliminating the need of contact protection circuitry or interposing relays.

Bestact can also be used in electronics component circuits. 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 sifnificantly better than both mercury relays and semiconductor relays.

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

Why is the contact resistance so low, and performance so stable?

Contact pressure is fixed, and furthermore the movable contact makes contact by a wiping action. In conventional reed switches, the electrical contact and magnet contact parts are common, so contact pressure changes with magnetic contact. And because it is a simple contact, changes in contact pressure large changes in contact resistance.
