Re: Canon 550d take photos continuously after testing DIY remote control

The schematics I saw all use DPST switch if one wants to focus and shot (shutter) at the same time. With this kind of switch, both focus and shutter are pulled down to ground simultaneously but in no time focus and shutter controls are tied (connected) directly at normal open (high) state, which I suspect would damage the camera circuit. Of course I could be wrong (about why using DPST switch or something equivalent) but then what else would cause problem?
