Query: No safety switch

This model does NOT come with a safety switch (model#554405 apparently does). It does not mention this anywhere in the product description, nor does it mention this in the installation instructions. It took me a frustratingly long time to figure out that the switch was actually not there. Without the safety switch, this in NOT a good pump for a furnace. The pump I was replacing had the safety switch hooked up to the furnace to turn it off if the pump failed...avoiding a big pool of water on the floor. I never would have ordered this model had I known there was no safety switch.
