a unique contact operating

For use in AC circuits, the  

relay is supplied with a  

built-in rectification circuit,  

thus retaining the high DC  

efficiency of the electro-  

magnet. The

 

current peak  

on energizing is also elimi-  

nated and consequently  

the relay can operate with  

a resistance in series (e.g.  

for high voltages or for  

arms used in conventional  

relays are eliminated.
