ULTRA-HIGH-SPEED MECHANICAL SWITCH, SWITCH FRACTURE THEREOF AND SWITCH CONTACTS THEREOF

摘要

An ultra-high-speed mechanical switch, a switch fracture thereof and switch contacts thereof. The ultra-high-speed mechanical switch comprises a casing that is internally provided with a first switch contact and a second switch contact. The casing is also provided with an operating mechanism for driving opening and closing. The first switch contact and the second switch contact are orderly provided with conductive metal pieces at intervals along the movement direction. Every two adjacent conductive metal pieces are mutually insulated. The conductive metal pieces have span length that satisfies the following conditions: at a closing position, the conductive metal pieces on the first switch contact are sequentially connected to two adjacent conductive metal pieces on the matched second switch contact in a spanning manner, and the first switch contact and the second switch contact are switched on; and at an opening position, at least one end of each conductive metal piece on the first switch contact is located at the interval between two adjacent conductive metal pieces on the matched second switch contact, and the first switch contact and the second switch contact are switched off. The opening and closing time of the ultra-high-speed mechanical switch is short, and the use requirement can be satisfied.
