| 摘要 | A seesaw switch comprises a rocking mechanism which includes concavely curved shoulders provided on both inner sides of the box of the switch, and a pushing rod carrier having convexly curved sliders at both sides of its lower part and fulcrum projections at both sides of its upper part. The pushing rod carrier is incorporated into the switch box so that the convexly curved slides seat on the concavely curved shoulders of the switch box and the fulcrum projections abut against the receiving stoppers of the frame of the switch. The vertically extending pieces of a button latch onto the upper part of the pushing rod carrier. | ||||||
| 权利要求 | 1. A seesaw switch comprising a rocking mechanism wherein the opposed, vertically extending, resilient pieces 11 and 11'' of a button 10 pass through the window 22 of a frame 20 to abut resiliently against the side edges of the opening portion 32 of a pushing rod carrier 30, the projections 34 and 34'' of the pushing rod carrier 30 being received under the receiving stoppers 23 and 23'' of the frame 20 to form a fulcrum, legs 37 and 37'' being provided at both sides of the cavity 35 in the lower portions of the pushing rod carrier 30, the lower parts of the legs 37 and 37'' constituting convexly curved sliders 38 and 38'', said sliders seating on the concavely curved shoulders 91 and 91'' provided on the inner side walls of a switch box 90, whereby said pushing rod carrier slides along a circular arc. 2. A seesaw switch as claimed in claim 1 wherein the vertically extendIng pieces 11 and 11'' are provided at their lower end with latching members 11a and 11a'', said members being adapted to abut resiliently against the side edges of the opening portion 32 of the pushing rod carrier 30. 3. A see saw switch as claimed in claim 1 wherein legs 12 and 12'''', and 12'' and 12'''' are provided at both sides each of the vertically extending pieces 11 and 11'' of the button 10, square posts 33, 33'', 33'''' and 33'''''' being provided at the four corners of the top surface of the pushing rod carrier 30, said legs 12, 12'', 12'''' and 12'''''' being adapted to abut against said square posts 33, 33'', 33'''' and 33'''''' respectively. 4. A seesaw switch as claimed in claim 1 wherein a central opening 32 is provided in the main body 31 of the pushing rod carrier, square posts 33, 33'', 33'''' and 33'''''' being provided adjacent the four corners of said central opening 32, semi-circular projections 34 and 34'' being provided in a central position between said posts 33 and 33'', and between said posts 33'''' and 33'''''' respectively, a cavity 35 being provided in a central area of the lower part of said main body 31, legs 37 and 37'' being defined by both sides of said cavity 35, the lower parts of said legs 37 and 37'' constituting convexly curved sliders 38 and 38'', and having holes 36 and 36'' which open downwardly. 5. A seesaw switch as claimed in claim 1 wherein the receiving stoppers 23 and 23'' of the frame 20 are defined by downwardly projecting bent portions provided in a central position of the side edges of the window 22 of the frame. 6. A seesaw switch as claimed in claim 1 wherein semi-circular projections are provided on both sides of the top of the body of the pushing rod carrier 30, said projections being adapted to contact the lower surface of the frame 20 to form a fulcrum for rocking of the pushing rod carrier. 7. A seesaw switch as claimed in claim 1 wherein the sliders 38 and 38'' of the pushing rod carrier 30 are provided with holes 36 and 36'' which open downwardly, springs 40 and 40'' being inserted into and mounted in said holes 36 and 36'' respectively, pushing rods 50 and 50'' being inserted into and mounted in said holes 36 and 36'' with said springs being compressed. |
