Yes, you can use the spade lugs as a disconnect. One problem that arises, if you fold the wings a lot like on the prototype, the spade terminal would spread, become loose and not make good contact. We would tighten it up and it would just continue, we had to replace the terminal often.

So I came up with the quick disconnect and the spring, that eliminated the problem of the terminals and has worked well on the prototype, my plane and others. The disconnect only works on float type senders, not on aerobatic tanks.

A couple of notes about them, the plate on the base and the screw holding it has to be electrically isolated from the fuselage or the sender wont work. The plastic spacer included does that, and has a plastic washer on the inside of the fuselage to prevent contact. The installation is easy, only difficulty is getting the screw from the sender through the center of the spring. Also don't want to over-tighten the screw, as you can damage the float as the internals can break loose and spin.

As with any spring, over time the spring can take a set, every year or two, you might need to stretch the spring a bit to make good contact, Typically this is once a year or two.
