This describes a dual electrode electrostatically deflectable deformographic switch. The switch can be driven by co-incident voltages and can be made to retain and store information. The switch can be used either as a display or a memory and has a number of engineering advantages, for it is a direct drive display which does not need either vacuum envelopes or electron beam drives. Furthermore, greater efficiencies can be realized and no refresh is necessary since the switch will operate in a standby condition. Also only two voltage levels above ground, i.e., a write voltage and a standby voltage, are required. The switch will enable copiers to be directly driven by computers.The switch can also be used as an optical waveguide transmit/receive switch or an accelerometer.
