Switch Control Activator Tool for the Handicapped

      A technique is described whereby a switch control
activator tool aids handicapped individuals to activate instruction
modules in the control of electrical devices.  The tool can be used
to control devices, such as computer settings, requiring either
two-dimensional or three-dimensional manipulation.

      The tool consists of two assemblies:  grid assembly 1 and
control activator 2, as shown in Fig.  1.  The tool is designed to be
held with either a hand, from an individuals mouth or controlled from
a head attachment.

      Grid assembly 1 contains a grouping of control modules 3, as
shown in Fig. 2, which are activated by control activator 2 so as to
direct the proper instruction to a computer.  Control modules 3 are
recessed in pockets 4 and along with fence-like protector 5 prevent a
user from inadvertently activating an adjacent control module.

      Control activator 2 consists of beveled sleeve 6, as shown in
Fig. 3a, actuating shaft 7 and compression spring 8.  Beveled sleeve
6 is first positioned, by the user, into appropriate control module
3.  When actuating shaft 7 is depressed, control module 3 activates
its internal switch, as shown in Fig. 3b.  When control activator 2
is removed from the module position, compression spring 8 allows
actuating shaft 7 to retract to its deactivated position.

      The primary purpose of the spring activation is to ensure a
positive intent to...
