White Emergency Lighting Double Pole Test Key Switch inc Key

Excellent. I wanted something that would disable some light switches in the hall, as I have the lights equipped with remote control bulbs, which require them to be always on. Does the job brilliantly and safely, while the key provided lets the switch be used when really needed (i.e. if changing the bulb). When not in use, the key can be kept in a safe place, or is small enough to hang safely behind a picture or something.

Performed exactly as required and compared to grid switches easier to install and MUCH cheaper

This is generally a good quality switch. My only complaint is that the pressed steel switch is quite insubstantial, thin and roughly finished. If you had it mounted on a keyring, I think it would likely get bent quite easily. It's certainly suitable for occasional use though.

I have converted the living room to Smart bulbs and I don't want people switching their power off so I have replaced the original light switch with this. I can use it to turn off the bulbs for maintenance or to reset them.

Does exactlyvas stated. good price too

Easy to install and good value

Used to replace a standard light switch for our outdoor security lights. The standard switch was at the same height as the bottom of a kitchen cabinet door and was turned off if it was opened fully. Problem now solved.

The trick with smart lighting is stopping people from switching power to the lights off otherwise they lose their connection to the hub controller.These switches are a godsend. I can keep the lights on and hide the key somewhere, forcing people to use my over the top elaborate HomeKit system.
