Worcester Circuit Board

Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a base board. The connector system uses P.C.B. strips with cut-out sections whose ends can easily be inserted in spring terminals, ensuring low contact resistance and ease of connection. The kit consists of : 1. Baseboard, plastic, with spring terminals and three battery holders. (1) 2. Batteries. (3) Lamps 1.25 V M.E.S. (10) 4. Lamp holders mounted on P.C.B. connectors. (6) 5. Plain connector P.C.Bs.
