MICRO-SWITCHES FOR DOWNHOLE USE

摘要

A downhole tool includes a device to be activated by electrical energy and a micro-switch that includes conductors and an element between the first and second conductors selected from the group consisting of: a dielectric element capab le of being modulated to provide a conductive path in response to receipt of electrical energy; and an element moveable in response to application of an electrical energy. The mic ro- switch may be formed of microelectromechanical system (MEMS) technology or microelectronics technology.
