The electro-mechanical 103 has a Timed Off Constant switch and a thumbwheel which allows early selection of future switching operations.All models show clearly the current state of the output.

Did what they said they would in a quick manner - first class service. Recommended!!!
The item was delivered at the time stated and was exactly as descibed on the web site. great service.
Service very quick,received the part in France within a few days,tracking number supplied immediately sale was realised.Price for shipping was reasonable too,not a rip off like some companies.If there is a downside,I had to communicate via e-mails as there was no phone number which for some people (me included) is a bit of a pain as I am not too internet savvy.however,would definitely use them again.
