マイクロ・スイッチの力学

抄録

One of the most important conditions that a microswitch should furnish is that the speed (cm/sec) of separation of contact electrodes at the instant of circuit cut-off is great. If the speed is great, shortening of the duration of arcing will reduce the wear on electrodes and prolong the life-defined by the number of operations-of the switch. For increasing the speed of separation, snap action of a spring system is taken up and, on a particular type of microswitch, this snap action is dynamically analyzed by calculating deformation energy of involved springs, contributing to the design of the switch. Similar analysis can be applied to any type of microswitch that is being used.
