Hi all,
I have a tank containing water and within this tank there is a large bilge pump that mixes the tank on activation..
I have a float switch the same as this one of which activates or deactivates another smaller pump

What is happening is when I turn on the big mixing bilge pump depndant on the tanks water level it is swirling the water around and triggering the float switch i.e knocking it up and down...what I need is a way of the float switch only to trigger when its been closed for a set time period i.e 30 seconds this way I can be sure when it triggers the smaller seperate pump it is doing so based on the water level in the tank rather than if the mixing pump is knocking the switch up and down.
Any ideas welcomed I am sure there is some kind of relay etc that only activates after a set time of being closed.
Thanks
