Top 5 Positive Customer Reviews for switch time
4 weeks delivery - mediocre... The product itself corresponds to the description. The only drawbacks (for my purposes) are: 1. the trigger signal by only ground level. It may be much helpful if users could have a possibility to have the trigger signal also by "+" level (which requires only penny-worth invertor). 2. the pre-set time period starts from moment the initial trigger signal becomes ground; no matter how long this trigger signal remains "zero", the relay releases in the pre-set delay time counted from the very first moment. I think more logical would be to start this count from the moment the trigger signal is over. Or to have a choice.
