The toggle switch to my Power-Flo LX Hayward Pump for my above ground pool has stopped working. I've located and ordered a replacement which is described as easy to replace. Is it really as simple as removing the outer case and using a screwdriver to press in the side arms to pop the old one out and then press the new one in? Already delayed starting the pump for one week due to slower shipping...water is green and I want to get it going as soon as the part arrives. Thanks for any responses.
