Why Choose Mercury Wetted?
Unlike dry reed relays, Mercury Wetted relays use a thin film of mercury to bridge the contact gap. This creates a “Self-Healing” liquid connection that offers unique advantages for critical test equipment.
Zero Contact Bounce
The liquid mercury dampens impact energy, eliminating signal chatter. Essential for high-speed digital testing.
Stable Resistance
Every switch operation renews the liquid surface, ensuring contact resistance remains low and stable for billions of cycles.
High Current Surge
Can withstand massive inrush currents (up to 100A for short pulses) without contact welding.
Position Sensitive
Note: Due to the liquid nature, standard mercury relays must be mounted vertically (within 30° of vertical).
