I'm new enough to this so excuse the lack of knowledge. I'm based in Limerick in Ireland. I'm looking to purchase a solid state relay for a project. Basically I'm trying to use the relay to switch on and off a 100w light bulb. I'm intending to use the mains as power (ac current). I understand the relay acts as a switch similar to a transistor. I've worked with transistors before. So essentially if you want to switch a 100w bulb at 240v the bulb will draw .41ma. (wattage divided by voltage). Once I do this I intend to switch the light bulb for a heat pad which draws 1.5 amps. What I'm really looking for is what relay to purchase. Any help on this would be greatly appreciated.
