The Mercury Advantage
Mercury wetted relays utilize a thin film of mercury to bridge the contact gap. This liquid connection provides unique benefits that dry reed relays cannot match.
- 01. Zero Contact Bounce: Clean signal switching essential for high-speed counting.
- 02. Stable Resistance: Liquid surface renews with every switch, preventing pitting.
- 03. High Surge Capacity: Withstands massive inrush currents without welding.
