When the click button is pressed, an associated post pushes down (1201b) on stem switch 1214 as shown in FIG. 12B.
FIG. 12C and FIG. 12E illustrate a cross sectional view of the tunable wheel assembly 1200 (FIG. 12A, as previously described above, shows the line for cross section A-A′), according to certain embodiments. The cross sectional view shown in FIG. 12C and FIG. 12E illustrate aspects of the A-type stem switch 1214 in conjunction with a sheet metal spring 1225 and contact pin 1226. FIG. 12C and FIG. 12E show A-type stem switch 1214 (for purposes of describing FIG. 12C and FIG. 12E, stem switch 1214 is the operating switch underneath a click button of the computer mouse), a rotatable wheel casing 1223 (with associated slots 1223a for stem switches), a stem cover 1219 (but the stem cover portion around the front half portion A-type stem switch 1214 is removed in order not to obscure the view of the components of A-type stem switch 1214 when working in conjunction with metal sheet spring), and rotatable wheel 1209, according to certain embodiments. FIG. 12C and FIG. 12E also show sheet metal spring 1225 (with an upper ear 1225a, a lower ear 1225b, and a contact point 1225c), stem foot 1214a (associated with stem switch 1214), spring 1220, contact pin 1226 (with associated contact point 1226c), travel limit stopper 1227 (associated with rotatable wheel casing 1223), housing 1224 (shown in FIG. 12C but not in FIG. 12E in order not to obscure the view of the sheet metal spring 1225 and contact pin 1226). Travel limit stopper 1227 limits the travel distance of stem switch 1214. Spring 1220 exerts a spring force against stem switch 1214 when stem switch 1214 is pressed down as described in greater detail below with respect to at least FIG. 12D. FIG. 12C and FIG. 12E show that stem switch 1214 is in the unpressed position. Thus, sheet metal spring ears (1225a, 1225b) push against stem cover 1219 and stem foot 1214a, respectively, and thus prevent contact point 1225c associated with sheet metal spring 1225 from contacting contact point 1226c associated with contact pin 1226. In the unpressed position of the stem switch, the position of stem foot 1214a relative to the position of the lower sheet metal spring ear 1225b affects the click-ratio (tactile effect) of the stem switch.
FIG. 12D and FIG. 12F illustrate the cross sectional view as described above but showing that A-type stem switch 1214 is in the pressed position. Housing 1224, as described previously, is shown in 12D but not shown in FIG. 12F in order not to obscure the view of the sheet metal spring 1225 and contact pin 1226 in FIG. 12F. In the pressed position, stem switch 1214 is pushed down against spring 1220 in slot 1223a (associated with rotating wheel casing 1223), according to certain embodiments. However, travel limit stopper 1227 limits the travel distance of stem switch 1214 in rotating wheel casing 1223. Further, as can be seen FIG. 12D and FIG. 12F, when stem switch 1214 is in the pressed position, stem foot 1214a is lowered in rotating wheel casing 1223. The lowering of stem foot 1214a, in part, allows the sheet metal spring lower ear 1225b to move forward towards the contact pin 1226. Thus, contact point 1225c associated with sheet metal spring 1225 makes contact with contact point 1226c associated with contact pin 1226, as shown in FIG. 12D and FIG. 12F.
FIG. 13A, FIG. 13B, FIG. 13C, FIG. 13D, FIG. 13E, and FIG. 13F illustrate the workings of some components of a tunable wheel assembly 1300, according to certain embodiments.

FIG. 13A shows that B-type stem switch 1315 is the selected switch setting positioned under the click button on the computer mouse. Rotatable wheel 1309 includes tooth slots 1309a and a tooth 1309b that can be moved from one tooth slot to another by rotating rotatable wheel 1309. Rotatable wheel 1309 can be rotated in order to change the switch settings and tooth 1309b locks the selected stem switch into position. FIG. 13A also shows the cross section line A-A′ that is associated with each of the cross sections shown in FIG. 13C, FIG. 13D, FIG. 13E, and FIG. 13F herein.
FIG. 13B illustrates a top perspective view of the tunable wheel assembly 1300, according to certain embodiments. FIG. 13B shows a rotatable wheel casing 1323, a housing 1324, a chassis 1318, rotatable wheel 1309, a stem cover 1319, A-type stem switch 1314, B-type stem switch 1315, and C-type stem switch 1316, according to certain embodiments. Rotatable wheel 1309 can be rotated (1301a) in order to position the B-type stem switch 1315 as the operating switch underneath a click button of the computer mouse (click button on computer mouse is not shows in FIG. 13B). When the click button is pressed, an associated post pushes down (1301b) on stem switch 1315 as shown in FIG. 13B.
FIG. 13C and FIG. 13E illustrate a cross sectional view of the tunable wheel assembly 1300 (FIG. 13A, as previously described above, shows the line for cross section A-A′), according to certain embodiments. The cross sectional view shown in FIG. 13C and FIG. 13E illustrate aspects of the B-type stem switch 1315 in conjunction with a sheet metal spring 1325 and contact pin 1326. FIG. 13C and FIG. 13E show B-type stem switch 1315 (for purposes of describing FIG. 13C and FIG. 13E, stem switch 1315 is the operating switch underneath a click button of the computer mouse), a rotatable wheel casing 1323 (with associated slots 1323a for stem switches), a stem cover 1319 (but the stem cover portion around the front half portion B-type stem switch 1315 is removed in order not to obscure the view of the components of B-type stem switch 1315 when working in conjunction with metal sheet spring), and rotatable wheel 1309, according to certain embodiments. FIG. 13C and FIG. 13E also show sheet metal spring 1325 (with an upper ear 1325a, a lower ear 1325b, and a contact point 1325c), stem foot 1315a (associated with stem switch 1315), spring 1321, contact pin 1326 (with associated contact point 1326c), travel limit stopper 1327 (associated with rotatable wheel casing 1323), housing 1324 (shown in FIG. 13C but not in FIG. 13E in order not to obscure the view of the sheet metal spring 1325 and contact pin 1326). Travel limit stopper 1327 limits the travel distance of stem switch 1315. Spring 1321 exerts a spring force against stem switch 1315 when stem switch 1315 is pressed down as described in greater detail below with respect to at least FIG. 13D. FIG. 13C and FIG. 13E show that stem switch 1315 is in the unpressed position. Thus, sheet metal spring ears (1325a, 1325b) push against stem cover 1319 and stem foot 1315a, respectively, and thus prevent contact point 1325c associated with sheet metal spring 1325 from contacting contact point 1326c associated with contact pin 1326. In the unpressed position of the stem switch, the position of stem foot 1315a relative to the position of the lower sheet metal spring ear 1325b affects the click-ratio (tactile effect) of the stem switch.
FIG. 13D and FIG. 13F illustrate the cross sectional view as described above but showing that B-type stem switch 1315 is in the pressed position. Housing 1324, as described previously, is shown in 13D but not shown in FIG. 13F in order not to obscure the view of the sheet metal spring 1325 and contact pin 1326 in FIG. 13F, according to certain embodiments. In the pressed position, stem switch 1315 is pushed down against spring 1321 in slot 1323a (associated with rotating wheel casing 1323). However, travel limit stopper 1327 limits the travel distance of stem switch 1315 in rotating wheel casing 1323. Further, as can be seen FIG. 13D and FIG. 13F, when stem switch 1315 is in the pressed position, stem foot 1315a is lowered in rotating wheel casing 1323. The lowering of stem foot 1315a, in part, allows the sheet metal spring lower ear 1325b to move forward towards the contact pin 1326. Thus, contact point 1325c associated with sheet metal spring 1325 makes contact with contact point 1336c associated with contact pin 1326, as shown in FIG. 13D and FIG. 13F.
FIG. 14A, FIG. 14B, FIG. 14C, FIG. 14D, FIG. 14E, and FIG. 14F illustrate the workings of some components of a tunable wheel assembly 1400, according to certain embodiments. FIG. 14A shows a housing 1424, a chassis 1418, a rotatable wheel 1409, a stem cover 1419, an A-type stem switch 1414, a B-type stem switch 1415, and a C-type stem switch 1416, according to certain embodiments. FIG. 14A shows that C-type stem switch 1416 is the selected switch setting positioned under the click button on the computer mouse. Rotatable wheel 1409 includes tooth slots 1409a and a tooth 1409b that can be moved from one tooth slot to another by rotating rotatable wheel 1409. Rotatable wheel 1409 can be rotated in order to change the switch settings and tooth 1409b locks the selected stem switch into position. FIG. 14A also shows the cross section line A-A′ that is associated with each of the cross sections shown in FIG. 14C, FIG. 14D, FIG. 14E, and FIG. 14F herein.
FIG. 14B illustrates a top perspective view of the tunable wheel assembly 1400, according to certain embodiments. FIG. 14B shows a rotatable wheel casing 1423, housing 1424, a chassis 1418, rotatable wheel 1409, a stem cover 1419, A-type stem switch 1414, B-type stem switch 1415, and C-type stem switch 1416, according to certain embodiments. Rotatable wheel 1409 can be rotated (1401a) in order to position the C-type stem switch 1416 as the operating switch underneath a click button of the computer mouse (click button on computer mouse is not shows in FIG. 14B). When the click button is pressed, an associated post pushes down (1401b) on stem switch 1416 as shown in FIG. 14B.
FIG. 14C and FIG. 14E illustrate a cross sectional view of the tunable wheel assembly 1400 (FIG. 14A, as previously described above, shows the line for cross section A-A′), according to certain embodiments. The cross sectional view shown in FIG. 14C and FIG. 14E illustrate aspects of the C-type stem switch 1416 in conjunction with a sheet metal spring 1425 and contact pin 1426. FIG. 14C and FIG. 14E show C-type stem switch 1416 (for purposes of describing FIG. 14C and FIG. 14E, stem switch 1416 is the operating switch underneath a click button of the computer mouse), a rotatable wheel casing 1423 (with associated slots 1423a for stem switches), a stem cover 1419 (but the stem cover portion around the front half portion C-type stem switch 1416 is removed in order not to obscure the view of the components of C-type stem switch 1416 when working in conjunction with metal sheet spring), and rotatable wheel 1409, according to certain embodiments. FIG. 14C and FIG. 14E also show sheet metal spring 1425 (with an upper ear 1425a, a lower ear 1425b, and a contact point 1425c), stem foot 1416a (associated with stem switch 1416), spring 1422, contact pin 1426 (with associated contact point 1426c), travel limit stopper 1427 (associated with rotatable wheel casing 1423), housing 1424 (shown in FIG. 14C but not in FIG. 14E in order not to obscure the view of the sheet metal spring 1425 and contact pin 1426). Travel limit stopper 1427 limits the travel distance of stem switch 1416. Spring 1422 exerts a spring force against stem switch 1416 when stem switch 1416 is pressed down as described in greater detail below with respect to at least FIG. 14D. FIG. 14C and FIG. 14E show that stem switch 1416 is in the unpressed position. Thus, sheet metal spring ears (1425a, 1425b) push against stem cover 1419 and stem foot 1416a, respectively, and thus prevent contact point 1425c associated with sheet metal spring 1425 from contacting contact point 1426c associated with contact pin 1426. In the unpressed position of the stem switch, the position of stem foot 1416a relative to the position of the lower sheet metal spring ear 1425b affects the click-ratio (tactile effect) of the stem switch.
FIG. 14D and FIG. 14F illustrate the cross sectional view as described above but showing that C-type stem switch 1416 is in the pressed position, according to certain embodiments. Housing 1424, as described previously, is shown in 14D but not shown in FIG. 14F in order not to obscure the view of the sheet metal spring 1425 and contact pin 1426 in FIG. 14F. In the pressed position, stem switch 1416 is pushed down against spring 1422 in slot 1423a (associated with rotating wheel casing 1423). However, travel limit stopper 1427 limits the travel distance of stem switch 1416 in rotating wheel casing 1423. Further, as can be seen FIG. 14D and FIG. 14F, when stem switch 1416 is in the pressed position, stem foot 1416a is lowered in rotating wheel casing 1423. The lowering of stem foot 1416a, in part, allows the sheet metal spring lower ear 1425b to move forward towards the contact pin 1426. Thus, contact point 1425c associated with sheet metal spring 1425 makes contact with contact point 1426c associated with contact pin 1426, as shown in FIG. 14D and FIG. 14F.
