Elkay Columbus Pneumatic Time Delay Switch
Going to cause you problems
I bought 4 of these to replace existing broken ones in a communal area in a block of flats.
2 worked fine.
the other 2 the time didn't adjust, regardless of what you did to the screw on the back, so even when set for the max (about 20 mins) they turned the lights off after about 10 seconds.
Local store staff were great as always in replacing these but it added a good hour onto my day and seeing a 50% fault rate has not exactly filled me with confidence and it wouldn't surprise me if they fail quickly.
Only way I could recommend these is if you are desperate and can't buy anywhere else, then buy 2 for every one you need as you will probably need them!

Columbus Pneumatic Time Delay
Ideal for the garage. I bought this to replace an existing one that has been working for more than 10 years in the garage. It was used to switch on two 100W bulbs, when required in the garage, but must not accidentally stay on for long, in order to reduce cost.

Not worth the money at all
We had three of these switchers and two of them broke after 1week, they are made of cheap plastic and the switch starts to get stuck after a normal usage.

Bought this switch as a direct replacement to replace one of the same type that was broken due to a lot of heavy use. The switch is reliable, and does what it was designed for. However I found the switch to be what I consider to be expensive for what it is.. Needs must I am afraid!!
