Patent ID: 7876185

Claim:
An electromechanical switch, comprising; a base portion comprising first and second electrical ports adapted to be electrically coupled in a plurality of modes; a first electromagnetic coil defining a longitudinal axis and adapted to receive a first energizing current; a second electromagnetic coil extending along the longitudinal axis in spaced apart relationship with the first electromagnetic coil, the second electromagnetic coil adapted to receive a second energizing current; an armature movable along the longitudinal axis relative to the first and second electromagnetic coils between a first stroke end position and a second stroke end position; a piston extending along the longitudinal axis coupled to the armature, the piston comprising a first rod having a first end and a second end and an actuator member extending substantially perpendicular from the longitudinal axis attached to the first end of the first rod; a first electrical contact element coupled to the first electrical port, the first electrical contact element is moveable from a first position to at least a second position in response to a force applied by the actuator member; a second electrical contact element coupled to the second electrical port, the second electrical contact element is moveable from a first position to at least a second position in response to a force applied by the actuator member; a third electrical contact element to couple to at least one of the first and second electrical contact elements; and first, second, and third dielectric carriers, each comprising a first end adapted to engage the respective first, second, and third electrical contact elements and a second end adapted to be engaged by the actuator member, each of the first, second, and third dielectric carriers selectively transfer an actuation force imparted by the actuator member to the first, second, and third electrical contact elements based on the energy state of the first and second electromagnetic coils; wherein the first and second ports are selectively coupled in any one of open-terminated mode, attenuation mode, and a short circuit mode based on the energy state of the first and second electromagnetic coils.
