Operations
Very high isolation voltages - up to 15kV are achieved through the use of high
vacuum reed switches with either rhodium
or tungsten contacts which make these
relays suitable for high reliability
applications, such as cardiac
defibrillators, test equipment and high
voltage power supplies.
The rhodium contact relays have low
contact resistance, while the tungsten
contact relays can switch higher voltages.
