ABSTRACT:
The disclosed invention includes a pair of spaced apart parallel plates with a plurality of reed switches lying between and perpendicular to these plates. One of the plates has a hole through it, and the reed switches are spaced around this hole at equal distances from each other. A control arm having a permanent magnet attached thereto protrudes through the hole. This magnet is used to close selectable ones of the reed switches by pivoting the arm about the hole to thereby move the magnet in close proximity with the selected switches.
