R could be very small, therefore the current and instantaneous power will be very large. Therefore you need more rugged/robust contacts, otherwise the contacts will wear-out over time. Or they could even weld together. | |

| Aug 26, 2017 at 12:39 | comment | added | Fed | I meant inrush current. Sorry. I corrected this in the question. I am trying to protect the LED strip from damage by the inrush current from the power supply. I have read this is important to do. Is it not? | |
