We see from your search that you're looking for information on the term "Electromechanical Relays",
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".
A few weeks before,
we featured the news release Soft starters incorporate a bypass contactor from
Carlo Gavazzi: "Carlo Gavazzi's RSHR-MIDI soft starters offer vibration-free starting with a dramatic reduction in mains dips and lamp flicker".
In June 2007, we covered the news from Crydom International
concerning its Crydom PCB electromechanical relays
- take a look at High-power switching comes in a small package
which says: "The silent operation and extremely long life expectancy of Crydom's solid-state relays makes them ideal for replacing PCB electromechanical relays".
Take a look also at the news release from Switchtec, Brochure dedicated to control and isolation,
as well as Safety upgrade provides reliability as a bonus from Pilz Automation Technology,
