Abstract
Abstract A touch button switch includes a light conducting body (10) having a conductive actuator (28) slidable from one end against a surface (62) to actuate a switch (61) on a board (52) which is held in place by hook laches (53) engaging mortises (55) in the circuit board. The circuit board has LEDs (58) which illuminate the rear edge of the body, which causes the light to be visible at its front surfaces 20, 21.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A touch button, comprising: a generally cylindrical body of light transmitting material having a light emitting edge at a proximal end thereof, having a plurality of hook latches extending longitudinally outward from a distal end thereof, having at least one stop surface near said distal end, having light receiving edge surfaces at said distal end, and having a bore axially disposed between said ends; a circuit board having a plurality of light-emitting diodes disposed on a surface thereof and having a mortise for each of said hook latches, said light emitting diodes positioned to illuminate said light receiving surfaces with said circuit board urged against said stop surface and said hook latches extending through said mortises and engaging said circuit board; and an actuator having a touch pad at a proximal end and a stem at a distal end, said actuator disposed within said body with said stem within said bore and said touch pad near said light emitting edge.
Claim 2
Dependent Claim
160 words
A touch button, comprising: a generally cylindrical body of light transmitting material having a light emitting edge at a proximal end thereof, having a plurality of hook latches extending longitudinally outward from a distal end thereof, having at least one stop surface near said distal end, having light receiving edge surfaces at said distal end, and having a bore axially disposed between said ends; a circuit board having a plurality of light-emitting diodes disposed on a surface thereof and having a mortise for each of said hook latches, said light emitting diodes positioned to illuminate said light receiving surfaces with said circuit board urged against said stop surface and said hook latches extending through said mortises and engaging said circuit board; and an actuator having a touch pad at a proximal end and a stem at a distal end, said actuator disposed within said body with said stem within said bore and said touch pad near said light emitting edge.
Claim 3
Dependent Claim
40 words
A touch button according to claim 1 wherein said actuator is slidable within said bore and further comprising: a switch assembly disposed on said circuit board to be operable by sliding said actuator to a distal position within said body.
Claim 4
Dependent Claim
20 words
A touch button according to claim I including a mounting flange extending radially outwardly of said body between its ends.
Claim 5
Dependent Claim
50 words
A touch button according to claim 1 wherein said body includes a finger extending longitudinally outward from said bore near the distal end of said bore and wherein said stem has a notch cooperating with the distal end of said finger so as to capture said actuator in said body.
Claim 6
Dependent Claim
27 words
A touch button according to claim 1 including a light shield comprising a tube of opaque plastic surrounding said light emitting diodes and said light receiving edges.
