The implant has an hermetically sealed enclosure and includes: (a) a micro-electromechanical switch (130) having, a suspension element on which is a ferro-magnetic layer and a moving switch contact and a fixed contact; a processing circuit (120) for the switch, and; a rate control circuit (102) for the implant, which responds to a switch signal by establishing an operating mode for the implant. The control circuit (102) is contained on a integrated circuit substrate and establishes an operating mode for the implant. The switch's (130) contacts are normally in a first position and are designed to pass into a second position when a magnetic field of a predetermined intensity is applied to the ferro-magnetic layer which causes the suspension element to move. The processing circuit, in response to the switch passing to its second position, delivers a switching signal, which is used by the rate control circuit to set a telemetry operating mode.
