摘  要

 隨著社會經(jīng)濟(jì)的發(fā)展，人民群眾生活水平不斷提高，繼電器在工程，機(jī)械，電子，電氣領(lǐng)域起著重要的作用，繼電器是一種電子控制器件，它具有控制系統(tǒng)（又稱輸入回路）和被控制系統(tǒng)（又稱輸出回路），通常應(yīng)用于自動控制電路中，它實(shí)際上是用較小的電流去控制較大電流的一種“自動開關(guān)”。故在電路中起著自動調(diào)節(jié)、安全保護(hù)、轉(zhuǎn)換電路等作用。
 從20世紀(jì)70年代前后發(fā)展出一種固態(tài)繼電器。固態(tài)繼電器是一種兩個接線端為輸入端，另兩個接線端為輸出端的四端器件，中間采用隔離器件實(shí)現(xiàn)輸入輸出的電隔離。隨著固態(tài)繼電器的普遍應(yīng)用，先后又有了常開觸點(diǎn)的固態(tài)開關(guān)，此開關(guān)的誕生在科技領(lǐng)域中有著非常重要的作用，具有普遍的現(xiàn)實(shí)意義。
 本文要在常開觸點(diǎn)的基礎(chǔ)上，研究一種具有常閉觸點(diǎn)的固態(tài)開關(guān)，以適應(yīng)市場及工程上的需求。

關(guān)鍵詞：常閉觸點(diǎn)、固態(tài)繼電器、開關(guān)

Abstract

 With the social and economic development, constantly improve people's living standards, the relay in the works, machinery, electronics, electrical play an important role in the field, the relay is a kind of electronic control devices, it has a control system (also known as the input circuit) and control system (also known as the output circuit), usually used in automatic control circuit, it is actually a smaller current to control a larger current "automatic switch." It plays in the automatic adjustment circuit, security protection, such as the role of the conversion circuit.    70s from the 20th century, before and after the development of a solid-state relay. Solid-state relay is a two input terminals for the other two output terminals for the four-terminal devices, the use of isolation among the input and output devices to achieve electrical isolation. With the widespread application of solid-state relay has normally open contacts and a solid-state switches, switch the birth of this field of science and technology has a very important role, is of universal relevance.    This article in the normally open contacts on the basis of the study a normally closed contact of the solid-state switch, in order to adapt to market and engineering requirements.
