Crumar Half Moon Switch

This is a special 3 way DPDT type switch used to select the 3 speeds of a rotary effect - Slow - Stop - Fast.
It is commonly known as a "half moon" switch, although it is more like a trapeze. Constructed of sturdy black painted metal, it comes with a TRS jack cable that connects directly to the instrument.
It can be fixed to the organ and positioned using the supplied screws.
