Evaluation was made with quality and workmanship due to the functionality and look at first short-term use. Long-term properties could not be evaluated. Product is used in hobby area (sports boat)
It concerns a Erstazlieferung. The installed in July 2016 Marco float switch was already broken. I have installed the new one but I will use it again only next year.
The shimmer switch works with a microswitch and a ball. The construction is robust, but not permanently waterproof. As it is always under construction due to its cable entry, this is a source of error. The seal is made only by a pressed rubber ring. After two seasons, the switch inside was damp and the contacts oxidized. No buy recommendation.
