crazy expensive switch

So is it really necessary to buy a $32 dollar switch?  In this case, although I suppose I should feel fortunate that it was reduced in price to about half that, if you add shipping it seems a bit spendy. My justification for this expenditure is that it will be used to control my autopilot and I foresee a moment in time when I may need to quickly disengage it so I need it to always work. Switches make me nervous and faulty ones make me really uncomfortable
