GENERAL INFORMATION
KU series vacuum switches are housed in pressed steel powder coated enclosure and are recommended for panel mounting or indoor service. The KU series vacuum switch has a SS316 welded diaphragm. KU series vacuum switches have passed the Helium leak test i.e. they are completely leakproof which makes it possible to achieve a full vacuum. The repeat accuracy is better than ± 1.5% FSR. The Pressure port is 1/4” BSPF standard.
