The electronic switches produce the classic tone of the siren. Need battery 4.5 V. The electronic packages have pre-printed “and pierced-boards” boards “. The circuits are already ready for immediate use. This ensures the success of the experiment by students even if they are beginners. The bolts and their associated electronics with spikes to prevent problems from any cold solder or failures and also there is special protection against short circuits. These reasons make them suitable and easy to use for students who have no experience in electronics. Other advantages of circuits is:
- Is made from high quality materials
- Have a four-page manual that explains the circuits and their Assembly (contains wiring diagram, floor plan of PCB and diagram of contents materials and their placement on the Board)
- They are small but easy to assemble
- Totally safe to use work with
- Operate with batteries 4.5V
- Low power consumption
