Review: It's as tough as old boots! - Well made thank you.
Review: Simple and effective - I bought this to control the boost function on my ventilation system which had, quite oddly, been originally installed with a momentary switch that had to be held down to use. It was a very straightforward swap from a practically equivalent existing switch - simply a matter of removing the wires from the old switch and attaching them to the corresponding terminals in this new one. The construction of this switch seems fairly simple but perfectly durable & reliable for my purposes in a low use domestic setting, perhaps a little pricy for what it is but not unreasonable for the benefits it provides. My biggest criticism is the process of adjusting the timings, although this isn't a huge issue. The time the button remains depressed is determined by how tight a screw on the back of the switch is set, and for anything under 5 minutes this is a fairly simple, if crude, adjustment. Precision is a bit tricky and there does seem to be a bit of inconsistency between presses, but this doesn't really matter for me. It is possible to set up to around 20+ minutes, although I found the difference between 5 and 20 min is only a quarter turn difference on the timing screw, so it does take some patience with trial & error to set it just right with longer times. Once set, it seems to work great. The mechanism is mechanical so there are no prone to fail electronics involved and there are no glowing LEDs which every electric equivalent to this product seems to be plagued with (I have plenty of those in the kitchen as is, no need for the walls to be glowing too).
