Abstract
An arc suppressor circuit for a relay includes a semiconductor means connected in parallel with the current carrying primary contact points. Auxiliary contact point means supply a gate signal to the semiconductor means to cause it to short the primary contact points during the closing or opening of the primary contact points. The circuit further provides for opening the auxiliary contact point means after the primary contact points are closed to prevent the semiconductor means from carrying load current for any substantial period of time. The semiconductor means may include a triac or a pair of silicon controlled rectifiers arranged to conduct on alternate half cycles.
