Abstract:
A microswitch, comprising:a substrate; a first electrode portion fixed to the substrate and having a first contact surface, the first electrode portion including a first layer formed of a first carbon series material and provided with a group of first fine holes extending to reach the first contact surface, and first metal segments formed of a first metal material and buried in the first fine holes, respectively; a second electrode portion arranged to face the first electrode portion with a gap provided therebetween and having a second contact surface movable toward the first electrode portion, the second electrode portion including a second layer formed of a second carbon series material and provided with a group of second fine holes each extending to reach the second contact surface, and second metal segments formed of a second metal material and buried in the second fine holes, respectively; and a deformable structure configured to support the second electrode portion on the substrate to face the second contact surface to the first contact surface with a gap in a non-contact state, and configured to be deformed to shift the second electrode portion and contact the second contact surface with the first contact surface in a contact state.
