jayachar88 0 Posted October 29, 2013 Share Posted October 29, 2013 Have some 5V SPDT EM-relay (called "sugar cube" relays), rated for ~240VAC-10Amps. To switch those, I believe I cannot directly connect them to the MSP430 launchpad I/O pins, right ? I need to use a BJT/FET -- mandatorily ? The 4 relays in turn control incandesent lamps. If anyone has a circuit schematic they could share, it would be very helpful. thanks, Jay Quote Link to post Share on other sites
