Procure now the 194L-HE6G-175, a premium 194L series control and load switch designed for versatile switching of small motors and control circuits. This Allen-Bradley device combines the functionality of a load break switch with the precision of a control switch in a compact, reliable package.
What Is the 194L-HE6G-175?
The 194L-HE6G-175 is a rotary cam switch belonging to the Bulletin 194L line. It is characterized by its adaptability, offering multiple pole configurations and switching angles. The 194L series is designed for lower current applications (up to 20A) compared to the 194E series, focusing on high reliability and specialized contact sequences. The «HE6G» refers to the handle and mounting style—typically a front-mount, grey/black 4-hole screw mounting—while the «175» indicates the specific internal contact diagram (likely a 3-pole ON/OFF 90° sequence). These switches are ideal for selector tasks, manual motor starting, and as local disconnects for auxiliary industrial equipment.

Advanced Control Architecture
The architecture of the 194L-HE6G-175 utilizes a cam-operated mechanism that ensures positive contact opening and closing. The contacts are silver-alloy based to provide excellent electrical conductivity and resistance to welding under inrush conditions. Its front-mount design with a clear legend plate allows operators to easily distinguish the switch position. The 194L series is particularly popular in global markets due to its compliance with both IEC and UL standards, making it a «world switch» for machine builders exporting to multiple regions.
Maintenance Tips
For the 194L-HE6G-175, maintenance is minimal due to the enclosed contact block. However, in environments with high levels of airborne contaminants or oil mist, inspect the front handle gasket annually to ensure it hasn’t become brittle. A degraded gasket can allow moisture into the control panel. Also, ensure the legend plate remains clean and legible; a quick wipe with a non-abrasive industrial cleaner is sufficient to maintain visibility for operators.
Frequently Asked Questions
Q: What is the difference between the 194L and 194E series?
A: The 194L is a cam-style switch suited for both control and load switching at lower amperages, while the 194E is a dedicated load-break switch designed primarily for motor isolation and higher current ratings.
Q: Can the contact sequence of this switch be modified?
A: No, the 175 contact diagram is fixed at the factory. If you require a different sequence (like Changeover or Multi-step), a different part number within the 194L family must be selected.
