Easier, quicker and cheaper to buy this whole assortment than to get just the few I needed from an electronics store.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
