42-24012-05 Pressure Switch
Pressure switch installed onto a Ruud 90 Achiever furnace, mounting holes didn't match, had to drill them out larger.
Wire connection spades were larger than original, had to crimp on new wire spade connections & install a longer hose from induction fan to switch.
Otherwise it functioned correctly.
