    Hi All.


    Looking for some recommendations of a decent, reliable AC timer. I have used the old fashions Arlec dial ones where you push in the pins for the times you want the power/lights to come on over the years, but after 10 years are not operating as well any more.
    I bought 2x of these: http://www.bunnings.com.au/hpm-7-day-digital-timer_p7034563
    I must have had too much turning on at once as they both seem to have blown and now will not turn off.


    Anyone else have recommendations of brand/model to use?

    The high inrush current (surge) of switchmode power supplies at turn-on can certainly cause timer relays to arc and stick on. The remote controlled switches can also have issues with loads like that. They often have a switching limit much lower than 10A.

    The mechanical timer is possibly better than a digital one in some cases. The switching contacts are simpler and may be more tolerant to the surge. I don't have anything to back this up though.

    I'd back this up with personal experience, does that count?!


    They all appear to be 10amp 2400w regardless of digital or not.

    Some of the older remote controlled outlets I had were 4A / 1000W max, so I wasn't sure if some of the digital timers might be the same.
