Siemens 52PT6GNA Oil Tight Push Button Switch

Siemens 52PT6GNA Oil Tight Push Button Switch is a 30 mm round push-button input in Siemens’ Class 52 family, designed for oil-tight service in harsh industrial environments. The actuator is round, and the switch provides On‑Momentary and Off‑Momentary (On‑Mom, Off‑Mom) functionality, allowing momentary ON or OFF operation depending on wiring. As part of the Class 52 lineup, the device is designed to withstand exposure to oil, water, and other contaminants and to resist corrosion, making it suitable for control panels in machinery, conveyors, pumps, and other automation equipment. The 52PT6GNA designation appears on distributor product pages (for example DigiKey) as the exact model name, confirming it as a standard Siemens component within the 30 mm push-button family. When selecting a robust, oil‑tight input for start/stop or interlock circuitry in industrial applications, the 52PT6GNA offers a compact, field-replaceable option that aligns with Siemens’ documented Class 52 specifications and terminology.
