We see from your search that you're looking for information on the term "Electromechanical Relay",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Novel relays stay in control for longer from
Watlow, which we summarised at the time by saying "Relays without No-Arc typically have a life cycle of about 100,000 cycles at rated amperage, whereas a No-Arc relay will have a life of more than four million cycles".
Several months prior to that,
we featured the news release High-power switching comes in a small package from
Crydom International: "The silent operation and extremely long life expectancy of Crydom's solid-state relays makes them ideal for replacing PCB electromechanical relays".
In May 2007, we covered the news from OEM Automatic
concerning its Crouzet hybrid power relay
- take a look at Power relay removes the need for a heatsink
which says: "Thanks to silent operation Crouzet's hybrid power relay is the ideal switching component for applications where absence of noise is of paramount importance".
Take a look also at the news release from Banner Engineering, Photoelectric sensors have universal appeal,
as well as Weight indicator ATEX certified for gas and dust from Weightron Bilanciai,
and Relays handle resistive and inductive loads from OEM Automatic.
