This paper will illustrate how the increasing electrical demands to power military and aerospace applications can successfully be met by high performance electromechanical relays. To meet these higher demands engineering compatibility must be properly understood between the intended application and relay switching performance parameters. With high performance electromechanical relays continuing to play a critical part in military and aerospace applications it is more important than ever before that engineers capture all of the military and aerospace electrical power requirements. A critical area within powering military and aerospace systems is capacitive load switching. Capacitive loads can generate high current levels that are transient in duration and adversely affect the relay at the component level and the military or aerospace applications at the higher systems levels. As capacitance increases the amplitude and duration of the current transient also increase.

With high performance electromechanical relays continuing to play a critical part in military and aerospace applications it is more important than ever that engineers capture all of the electrical power switching requirements. A critical area within powering military and aerospace systems is relay life when capacitive load switching. Capacitive loads generate high current levels that are transient in duration and often adversely affect the relay lifespan at the component level and the military or aerospace application reliability at the systems level.

This paper will illustrate how the increasing electrical demands of military and aerospace applications can successfully be met by high performance electromechanical relays. To meet these higher demands engineering compatibility between the intended application and relay switching performance parameters must be properly understood. One of the critical parameters are inductive loads which generate transients that can adversely effect relays at the component level and the military or aerospace application at the higher systems levels. In this paper the impact of several methods of inductive suppression are explored. Diode, zener diode, transient voltage suppressors all provide methods to control polarity and voltage levels generated by collapsing magnetic fields in deenergized inductive devices.
