| 摘要 | A switch is provided which is shielded against the passage of electromagnetic energy and is composed of a switch case, a switch lever in the switch case and a flexible electromagnetic radiation shielding boot attached to said case and encasing and shielding the switch lever to prevent escape of electromagnetic radiation through said switch. The boot has a resilient electrically insulating outside jacket and an electrically conductive wire mesh inside lining fitting within the jacket and over the lever. | ||||||
| 权利要求 | 1. In an electronic device, an electromagnetic radiation shielded toggle switch having a switch case, a switch lever in said switch case, and a flexible, electromagnetic radiation shielding boot attached to said switch case which covers and shields said lever from electromagnetic radiation, said boot having a resilient, electrically insulating outer layer and a conductive wire mesh inside liner. 2. The toggle switch of claim 1, wherein said insulating outer layer is a silicone rubber. 3. The toggle switch of claim 1, wherein said insulating outer layer is neoprene. 4. The toggle switch of claim 1, wherein said wire mesh liner is a knitted wire mesh. 5. An electromagnetic radiation shield boot for toggle switches Having a resilient, electrically insulating outer layer and a wire mesh inner liner. 6. The boot of claim 5, wherein said resilient outer layer is a silicone rubber. 7. The boot of claim 5, wherein said resilient outer layer is neoprene. 8. The boot of claim 5, wherein said wire mesh inner liner is a knitted wire mesh. 9. An integral electromagnetic energy radiation boot shield for toggle switches having a conductive wire mesh inside liner comprising a crown and a compacted integral annular rim having a greater outside diameter than the outside diameter of the crown and a greater thickness than the crown. 10. In an electronic device, an electromagnetic shielded toggle switch having a switch case, a switch lever in said switch case, and a flexible, electromagnetic radiation shielding boot attached to said switch case which covers and shields said lever from electromagnetic radiation, said boot having a resilient electrically insulating outside jacket, an electrically conductive knitted wire mesh inside lining fitting tightly within said jacket and tightly over said lever. 11. In an electronic device, a shielded switch having a switch case, a movable switch actuating member in said switch case, a flexible shield covering and shielding said switch actuating member and including a layer of electrically conductive material in contact with said case to prevent passage of radiation through said case, said shield flexing with movement of said actuating member to allow operation of said switch. 12. A switch as claimed in claim 11, in which said layer of electrically conductive material is in contact with said switch actuating member so as to prevent radiation from said member. 13. A switch as claimed in claim 11, in which said layer of electrically conductive material is covered with a resilient, electrically insulating material. |
