Extensively, conventional relay construction is all electromagnetic type, is exactly that AC and DC power supply passes through iron-core coil and generates magnetic, drives
Contact executes opening and closing work, when needing continuous loading, it is necessary to have one group of contact to carry out state holding.In recent years, have new
Bistable relay developed, their some keep using mechanical mechanism and discharge operating contact；Some using twin coil come
It controls relay and realizes bi-stable effect.
However all there is larger drawbacks for these bistable relays in the prior art, mechanical mechanism first is easy tired
Labor, reliability be not it is fine, often tens times, hundreds of tasks cannot keep synchronous regime, cannot be used in height from
In the equipment of dynamicization, machine unit, which has been eliminated.And driving is controlled using twin coil, it is manufacturing and is applying
In scope and sufficiently complex, the scope of application is small.
Also developed a bistable relay, really a circuit plate module in the prior art, by electronic component and
Conventional relay assembly is in a wiring board, using binding post and button as external input and function end, although function
Reach, but actual use is very inconvenient, more since original paper is more, failure rate is also higher, and the popularization effect of larger area is not achieved
Fruit.
