Crumar HMS-20-BK Halfmoon-Style Selector

This is a special 3-way DPDT type switch used for switching between the 3 speeds of a rotary effect - SLOW - STOP - FAST. It's commonly known as an "half-moon" switch, even though this one is more like a trapezoid. Built in solid black coated metal, comes with a TRS jack cable that connects directly to the instrument. It can be attached to the organ and positioned using the supplied screws.
