Centralab PA rotary switch is a 5-pole, 3-position non-shorting selector switch featuring steatite ceramic insulation. The non-shorting designation indicates break-before-make operation, ensuring the current circuit opens before a new one is connected to avoid momentary cross-contact. This switch is suitable for multi-circuit selection in electronics where reliable isolation between poles is required. Use cases include control panels and instrument assemblies that rely on a rotary switch to route signals across multiple circuits.
