Abstract
A MEMS switch includes: a housing, a switching assembly; a first actuation electrode, a first contact, a second contact, and a second actuation electrode. The switching device has a stress gradient along the thickness direction, such that in response to applying no voltage between the first actuation electrode and the second actuation electrode, the switching assembly contacts with the first contact. In response to applying a first voltage between the third actuation electrode and the fourth actuation electrode, the switching assembly is driven to deflect such that the switching assembly is spaced apart from both the first contact and the second contact. In response to applying a second voltage between the third actuation electrode and the fourth actuation electrode, the switching assembly is driven to deflect such that the switching assembly contacts with the second contact. The first voltage is smaller than the third voltage.
