Emerson’s TopWorx™ GO™ Switch is an extremely versatile sensing solution designed for the most challenging environments and applications. It detects like a proximity switch and functions like a limit switch, providing higher reliability when conventional switches fail. GO Switch provides reliable, durable proximity sensing in the most demanding conditions, and its innovative, unique design provides simplified, maintenance-free high performance.
GO™ Switch model 31 is the ideal replacements for traditional mechanical limit switches. Sealed contacts, rugged housings, non-contact detection of ferrous metal & magnetic targets, and snap action response make this switch the ultimate problem solver for troublesome mechanical limit switch applications.\
TopWorx™ GO™ Switch provides maintenance-free reliability, unique design and simplified operation where conventional switches fail.

Q & A
GO™ Switch Model 31 Limit Switch - Proximity Sensor Q & A
Manufactured by TopWorx, a brand of Emerson, the GO Switch combines the reliability of a proximity sensor with the simplicity of a mechanical limit switch.
The GO Switch Model 31 is specifically designed as a drop-in replacement for mechanical limit switches, offering several key advantages:
- Maintenance-free operation (no moving parts)
- Sealed contacts that resist moisture, dust, and corrosion
- Snap-action response for consistent switching
- Higher reliability in vibration-heavy or low-cycle applications
- Long service life in extreme temperatures and hazardous areas
For applications where mechanical switches frequently fail due to wear, contamination, or misalignment, the GO Switch Model 31 delivers a far more durable solution.
Yes. The GO Switch Model 31 is intrinsically safe and certified for use in a wide range of hazardous locations, including:
- Class I, Div 1 & Div 2
- Class II, Div 1 & Div 2
- Class III
- Zone 0 (Intrinsically Safe)
These certifications make it ideal for oil and gas, chemical processing, mining, grain handling, and other explosive or dust-prone environments, where safety and reliability are critical.
The GO Switch Model 31 offers flexible wiring and electrical configurations to simplify integration:
- SPDT dry contact output
- Rated up to 3A at 240VAC, 6A at 120VAC, and 2A at 24VDC
- AC/DC operation
- Normally Open (NO) or Normally Closed (NC) wiring
- Lead wires, cables, or quick disconnects (micro or mini)
This versatility allows the switch to work seamlessly with PLCs, control panels, and legacy systems without additional signal conditioning.
The GO Switch Model 31 excels in challenging industrial environments, especially where access is limited or maintenance is difficult. Common applications include:
- Valve position sensing
- Conveyor and material handling systems
- Rotating or vibrating equipment
- Remote or infrequently operated machinery
- Outdoor or washdown environments
- Extreme temperature installations (-50 °C to 105 °C)
With a 6 mm (1/4 in) sensing distance, rugged housing options including stainless steel, and gold-plated contacts, it is engineered to perform where conventional switches fail.
