一种显示和操作元件（12）中描述，其包括多个可能相互触发一个可插入的照明按钮到壳体卡，这些照明按钮的功能和可能gewüschte互相触发电几乎通过电路来确定的，该装置 HZW。 设置不改变布线布置在所述插入式卡编码开关矩阵基板上装置跳线0等。，或者由微处理器编程是可调节的，其优选容纳在专用插卡。 对于较大的系统，以被控制到多个这样的元件在壳体组合以及可能还有多个这样的外壳可以连接到彼此经由数据线，其中它是有利的，以适应微处理器在中央壳体（60）和要被用于所有的显示和 控制操作元件相对于它们的功能和相互触发集中。 显示衣服致动器替换，因为它的多功能性，该日期的时所使用的例如用于空调，必要不同的显示和操作元件，从而导致显著成本节约在两个控制装置的方面，以及关于它们的建造和维护控制系统。

A display and operating element ₍₁ 2) is described, comprising a plurality of possibly mutually triggering illuminated pushbuttons on an insertable into a housing map, the function of which illuminated pushbuttons and possibly gewüschte mutual release is electrically almost accomplished by using circuits whose arrangement HZW. Setting without wiring modification means arranged on the riser board coding, crossbar switch, jumpers o. The like. Or by programming a microprocessor can be adjusted, which is preferably housed in a special plug-in card. For larger systems to be controlled to a plurality of such elements can be united in one housing and possibly combine several such housing to one another via data lines, it is expedient to accommodate the microprocessor in a central housing (60) and to use it all the display and controls with regard to their function and mutual triggering centrally control. The indicating ung operating element replaced because of its versatility, the date when control systems, which are used for example for air conditioning systems, you need different display and operating elements and this results in a significant cost savings in terms of both control devices as well as to their construction and maintenance.
