A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When setting the
jumpers, ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on
both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin,
the jumper is OPEN. Please see the following illustrations
