TopWorx GO Switch limit switch | 11-11120-00, SPDT 10 A, magnetic sensing, NEMA 6P, −40 to +105°C
The TopWorx GO Switch is a magnetically actuated limit switch developed for valve position applications in the petrochemical and energy industries. The 11-11120-00 belongs to the Model 11 heavy-duty series: magnetic sensing means the switch does not need physical contact with the target, the 316L stainless steel housing resists corrosion, NEMA 4X / 6P protection withstands high-pressure washdown, and the operating temperature range of −40°C to +105°C (optional up to +176°C) covers high-temperature piping in petrochemical plants.
Note: non-contact magnetic sensing, for frequent valve open / close position detection.

Magnetic sensing vs. mechanical limit switches
Mechanical limit switches need physical contact to actuate. The GO Switch senses magnetically without touching the target, which suits the following:
- Valve position: open / closed position detection on butterfly and ball valves; valve body vibration does not affect sensing reliability
- Petrochemical piping: 316L stainless steel resists corrosive media such as H₂S and Cl⁻, for offshore platforms and refineries
- High temperature: +105°C standard version, or +176°C high-temperature option, for installation around steam lines
- Frequent operation: suits automatic control valves that open and close many times a day
