Mercury Wetted Reed Relays from Pickering Electronics
Mercury wetted relays remain a good choice for some applications due to the fact that they have no contact bounce, have a high power rating and offer a very low and stable contact resistance, with over one billion operations.
While they do not meet the requirements of the RoHS directive, there are many applications that are exempt from this, for example, medical equipment, instrumentation, military applications, servicing, upgrading or expanding pre RoHS equipment.
One special application involves relays featuring two change-over switches with a common open time. These are used in data acquisition systems using the ‘Flying Capacitor’ technique, this gives superb isolation between the source and the device measuring it.
