Abstract
A switch having spaced apart conductors with a high resistivity gate member therebetween. First and second mercury droplets are respectively connected to the ends of the conductors. When a control signal is applied to the gate member, the mercury droplets are drawn to it and establish electrical connection between the conductors to close the switch. Upon removal of the control signal the mercury droplets separate and assume their initial droplet form thus opening the switch.
