Abstract
Abstract A thin-type switchboard having a plurality of reed switches each of which is adapted to be operated when subjected to a magnetic field, said reed switches being disposed substantially in a single plane beneath an operating surface. A separate manually positionable permanent magnet operates selected ones of said reed switches when positioned in registration therewith adjacent said operating surface.

Claim 1
Independent Claim
158 words
A thin-type switchboard comprising a plurality of reed switches operable in response to a magnetic field; case means having an operating surface, said reed switches being positioned in an array adjacent one side of said operating surface; and a manually positionable permanent magnet means adapted to operate selected ones of said reed switches when manually positioned adjacent the other side of said operating surface in registration with said one of said reed switches, said permanent magnet means being selectively manually positionable adjacent each of said reed switches to operate said switchbOard, said other side of said operating surface being defined by an elastic substance having a contact surface, said reed switches being positioned relative to said elastic surface contact surface so that said permanent magnet means effects operation of said selected ones of said reed switches only when engaged against said contact surface and pushed into said elastic substance at a point in registration with said reed switch.
