Correction, I quoted the wrong price: Honeywell's 4TL837-3D, which is the switch in the 787s according to the SAIB "EASA_SIB_NM-18-33_1-1.pdf", costs about 1300€. MIL-spec &c. certifications are costly. Still cheap enough to not risk killing hundreds of people with the flick of a wrist. Sorry about that.
