WORCESTER CIRCUIT BOARD

To explore the nature and properties of electricity by using simple circuits which are easily constructed on a base board. The connector system uses p.c.n. strips with cut-out sections whose ends can easily and quickly insert in spring terminals, ensuring low contact resistance and good electric contact.
