Sangamo PSB Powersaver Boost Run Back Timer Switch 0.5 Hour - 2 Hour

Sangamo are a great maker of high quality devices. I know a little about building electronics and opened up the back of the switch before installing it. You'll find only high-quality components on the PCB - often better than other makers. The core to this is the Omron relay that Sangamo use for this switch. It's a high-end relay capable of delivering 16 amps without overheating - you'll see that other makers often rate their devices only for 13 amps even if using 16 amp relay which allows them to pass safety tests at much lower amperage and heating levels.All round solid quality, simple install, and exactly the functionality you expect of a timer switch.
