Locktronics is a range of products that simplifies the process of learning and teaching electricity and electronics. The core range consists of more than 200 electronic components (ANSI and DIN) mounted on rugged plastic carriers which are printed with the corresponding circuit symbol. Students use these carriers, in conjunction with a baseboard with interconnecting metal pillars, to build up a working circuit. They then use the curriculum provided to carry out experiments in electricity and electronics. A key benefit of Locktronics is that as students construct the working circuit they can also see the corresponding circuit diagram.
