Blue SPST on-off round hole illuminated automotive rocker switch
The round hole design makes installation much easier than for most rocker switches, requiring only a 1/2” diameter hole. One of this series is non-illuminated, but the others have one extra terminal (total: 3 terminals) to connect to ground for the light. This is an attractive series; lighted switches having a “glo”.
