On the 27SC we owned, the power lift toggle had a spring and returned to center. It was very much just a DPDT switch. You can find a replacement at most good old fashioned hardware stores, or a Grainger is you have one close by.
I would remove the old one first, it should be the tab terminal style and they could match it for you easily.
