用于微型继电器的致动器的设计基本上取决于可靠操作所需的力。这些力是在Au，AuNi 5和Rh接触样品实验确定的。接触电阻测量接触力连续变化的范围从0.1 mN到超过10 mN。通过一种新的原位清洁方法，称为“Schaltreinigung”程序，实现了样品的清洁度接近微型继电器内的接触。在微型继电器中使用的非常合适的接触材料被发现是AuNi 5和Rh，而Au不是由于其高粘附性。在AuNi 5和Rh的情况下，分别通过小于0.5 mN和0.9 mN的力实现可靠的操作。实验结果为微继电器驱动器的开发和优化提供了基础设计数据。(C)1999年Elsevier Science S.A.

The design of an actuator for a microrelay substantially depends on the forces required for reliable operation. These forces were determined experimentally at Au, AuNi5 and Rh contact samples. Contact resistance was measured with contact forces varying continuously in the range from 0.1 mN to more than 10 mN. Cleanness of the samples close to that of the contacts inside a microrelay was achieved by a new method of in situ cleaning, called the 'Schaltreinigung' procedure. Well-suited contact materials for use in a microrelay were found to be AuNi5 and Rh, whereas Au is not due, to its high adherence. In the case of AuNi5 and Rh reliable operation is achieved by forces smaller than 0.5 mN and 0.9 mN respectively. The experimental results provide the basic design data for the development and optimization of microrelay actuators. (C) 1999 Elsevier Science S.A. All rights reserved.
