This switch was original equipment in my shower sump and in the 5 years I've owned this boat I've replaced the switch 3 times. The switch works for a short period of time and then will not activate when the water level rises above the float. Slight upward pressure activates the switch but the leverage from the float is insufficient to make the contact. I'm currently looking for something that does NOT have mechanical contacts. Lets hear it for the good-old-days of mercury switches
In a shower sump. I replace the float every year or two. The float will be completely under water and it will not turn on the pump. By very lightly manually lifting the float the switch then will click and it works, for 1 cycle. The float works fine but after time the switch gets harder to press. Definately has a switch design issue. All 7 or 8 I have replaced have had the same problem in about a year..
The product is in an A/C water sump. Custom fitting requires replacement with exact duplicate. Durability less than one season. Fails to turn on and empty sump even after constant cleaning and maintanance. Have replaced five switches in five years.
