摘　　要：揿压式旋转转换开关适合于电路转换用,也可作通断用。结构小巧,适用范围广,开关寿命2万次,工作范围:DC 6A 125V或DC 3A 250V。键杆行程为2.5mm。操作力为4±0.5N。嵌件的设计,旋转接触片和旋转机构的设计为设计的关键。保证每揿压一次开关键帽,接触簧片旋转45°进入下一接触区。Press & Turn Changing Switch is suitable for use of circuits changes and also for use of on and off. The structure is small with wide applications. The life of switch is 20,000 times, with working range:DC6A 125V or DC 3A 250V, the travel distance of key bar is 2.5 mm, with operation force at 4±0.5N. The design for inlaid pieces, rotation contact piece and rotation mechanism is the key points for design, so as to assure every time of press on the switch key cap, the contact spring piece to turn 45° to enter into next contact area.
