In the Body Detector circuit, there are some of the components that we had changed. It is such DIP switch that suppose is 3-pole 4-way rotary switch. The reason why we change this component is because we want to make the circuit more easy to dealing with. Beside it also easier us to construct on the PCB board. The actual switch is actually the rotary switch which is it can be rotate or turn over it due to the function mode of "sleep", "activate" and "adjust". However, since the switch size was too big to be put in the circuit, so that me and my partner decide to change it with the another switch that equivalent to. The DIP switch that we changed also have the 4-way button but it only need to be press up and down to On and Off it.
