Mercury Wetted Technology

The “Zero Bounce” Phenomenon

In standard dry reed relays, when contacts close, they physically bounce apart several times before settling. This creates electrical noise which can disrupt high-speed digital signals.

Mercury Wetted Relays eliminate this. A thin film of mercury covers the contacts. When they close, the mercury bridges the gap instantly. If the contacts bounce, the mercury bridge stretches but does not break, maintaining a continuous electrical path.

High Power & Long Life

The mercury film refreshes the contact surface with every operation, preventing pitting and welding. This allows mercury relays to switch much higher power (up to 100W/5A) compared to dry reeds and last for billions of cycles.
