故在电路中起着自动调节、安全保护、转换电路等作用。在大多数的情况下，继电器就是一个电磁铁，这个电磁铁的衔铁可以闭合或断开一个或数个接触点。当电磁铁的绕组中有电流通过时，衔铁被电磁铁吸引，因而就改变了触点的状态。继电器一般可以分为电磁式继电器、热敏干簧继电器、固态继电器等。本实验板上配置的继电器如图9-15。图9-15继电器实物图继电器也是属于感性器件，所以不能用单片机的I/O口直接来控制，且要在三极管等控制器件上加反相保护电路。一般实验中都是单片机通过一个PNP型三极管，把三极管作为电子开关来驱动继电器，继电器的开和关完全由三极管的基极电平进行控制。当三极管基极为高电平，PNP型三极管截止，这时继电器不工作；反之为低电平的话，PNP型三极管导通。
指示灯采用本实用新型的技术方案，具有以下有益效果：本实用新型的技术方案，通过在壳体凹设有一沿长度方向延伸且与压电陶瓷片相适配的呈圆环形的共振腔，压电陶瓷片可拆卸的嵌设于共振腔内设置，后盖可拆卸的嵌设于共振腔的后端开口处设置，插脚平行的凸设于后盖的后端面设置，且插脚与压电陶瓷片电性连接，壳体的下端外周壁设有安装板，壳体的后端面外周壁对称的凸设有第二安装板，安装板分别与第二安装板垂直连接，安装板的两端分别对称的凹设有安装孔，第二安装板凹设有第二安装孔，使得蜂鸣器组装装配方便快捷，并且通过插脚、安装孔以及第二安装孔，便于蜂鸣器的快速安装，方便后期维护，提高了工作效率，实用性强，而且无电磁线圈和动圈，不必担心绝缘恶化，并无漏电的可能，同时该压电式蜂鸣器具有体积小、重量轻、厚度薄、灵敏度高、耗电省、可靠性好、造价低廉以及良好的频率特性的特点。为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下。如果给预直流信号蜂鸣器是不响应的，因为磁路恒定，钼片不能振动发音。
