RT22-4070-A31NB and RT22-4070-A317B are vacuum contactors with DPDT contact arrangements. These units can also be used as SPDT contactors by wiring the contacts in parallel. These contactors are commonly used in antenna switching for high power RF circuits, such as those encountered in transmitters.
