High Voltage Relays
The power industry uses many types of high voltage relays for signal switching as well as high current switching, in various single and multi-pole types. Special multi-pole high voltage relays with more than one normally closed and normally open contacts in a single package are also useful in areas where a certain load needs to be switched on before switching off another one. Special reed switches with high breakdown voltage, capable of switching high wattages are used to manufacture relays that can carry as high as 5 amps. Multiple reed switches can be used in reed relays to manufacture different contact forms, for example, two Normally Open contacts and three Normally Closed contacts which can be actuated with voltages as low as 5 volts. These kinds of relays not only save power, but can also simplify circuit switching logics.
