Abstract:
A mechanical portion of a rear-mount integrated rotary encoder for use with a circuit board having an encoder contact pattern formed thereon, comprising:a housing having a rear surface, a side surface, and a substantially open front area; a rotatable shaft extending substantially orthogonally through said open front area of said housing; a rotatable circuit contacting member mechanically connected to said shaft; and a securing device for securing said mechanical portion to said circuit board; said rotatable shaft being passed through an aperture in said circuit board such that said rotatable circuit contacting member contacts said encoder contact pattern; a knob mounted to said shaft for rotating said shaft; an elastomeric button having an aperture for receiving said shaft, said elastomeric button being mounted between said circuit board and said knob, and when so mounted exerting a force against an underside of said knob; and a pair of switch contacts mounted between an underside of said elastomeric button and said circuit board; said switch contacts being changed between an open state and a closed state by sliding said knob along said shaft.
