Product family overview
Mercury Wetted Relay HGFR application and selection guide
Mercury wetted relays provide stable low contact resistance and extremely low or bounce-free switching behavior for specialized precision measurement and test applications where signal integrity is critical.
Use this family where bounce performance and contact stability are more important than a general-purpose relay solution. Confirm orientation, regulatory and application limits before production use.

Engineering selection notes
Before choosing a model
These notes keep product pages useful for engineers while avoiding overclaims. Final ratings remain model- and application-specific.
Series comparison
Mercury wetted relay series comparison
Use this table to choose the starting series before checking the individual model datasheet for coil, contact form, orientation and regulatory suitability.
| Series | Best fit | Switching behavior | Selection focus |
|---|---|---|---|
| HGFR | Fast precision signal switching | Low bounce mercury wetted contact | Confirm coil voltage, contact form and mounting orientation |
| HGMR | Measurement and instrumentation switching | Stable low contact resistance | Confirm signal level, life requirement and package constraints |
| HGSR | Sensitive / compact mercury relay applications | Repeatable low-level switching | Confirm footprint, orientation and environmental limits |
| HVR / related | Higher voltage precision switching | Family-specific ratings | Check datasheet before replacing with general reed relay |
