Is there a way to better test or adjust that booster pump switch?

All I know, so far, is that when I manually press down on the complicated
intermeshed switch levers with a stick, the switch sparks green and
instantly activates the booster pump which stays running for about 4
minutes which gives the house water pressure for about three or four
showers worth of water.

But the switch no longer turns on by itself anymore.

What else can I test or adjust?

A quick check shows them available at Ace Hardware and Lowes. $25
to $35.
A shade tree fix would be some lubricant on the moving mechanism.
