Wherein, the 3rd transmission plane 451 be positioned at above SMDIR pipe 201 is input face, and the second collimation convex surface 452 is for collimation, and the first horizontal input face 453 is also input face, is positioned at the 4th Fresnel surface 455 above SMDPT pipe 202 for optically focused.
Described 3rd optical module 45 be positioned at together with the first plane mirror 442 on the right side of the first briquetting 14, form the control to key switch conducting and disconnection.First plane mirror 442 is in button pressed and when loosening, and carry out motion that is descending and that rise, the light path between itself and the 3rd optical module 45 realizes conducting or disconnection, thus realizes "ON" and the "Off" of key switch.
When button does not have stressed pressing down, the level crossing 442 linked together with the first briquetting 14 is in top position, its second plane mirror 454 not being positioned at lower position with right side is aimed at, after the light of SMDIR pipe 201 injection passes through the 3rd transmission plane 451 incidence above it, incident ray collimates through second of top the collimation convex surface 452 again, and the light after collimation exports upward.Collimated ray incides and is in the first plane mirror 442 of top position, after its reflection turnover, along the direction of level toward the outgoing of right.Because the first plane mirror 442 is not aimed at second plane mirror 454 on right side, the light being reflected turnover by the first plane mirror 442 can not be reflected by the second plane mirror 454, light can not be coupled in the SMDPT pipe 202 below it, light path is in off-state, and the circuit be attached thereto can not trigger current.
When button is stressed press down time, slidingtype lever actuating mechanism pushes the first plane mirror 442 be positioned at below the first briquetting 14 to lower position.Now the first plane mirror 442 aligns with the second plane mirror 454 being positioned at right side, after the light of SMDIR pipe 201 injection passes through the 3rd transmission plane 451 incidence above it, the second collimation convex surface 452 again through top collimates, and the light after collimation exports upward.Export light on the first plane mirror 442 of top, after its reflection turnover, the direction along level is penetrated to the right.Because now the first plane mirror 442 aligns with second plane mirror 454 on right side, the light being reflected turnover by the first plane mirror 442 is reflected by the second plane mirror 454, below directive, assembled by the 4th Fresnel surface 455 further, light after convergence focuses in the SMDPT pipe 202 below it, light path is in conducting state, the circuit triggers electric current be attached thereto.
