ABSTRACT:
A device which provides a plurality of actuator members, for effecting switch closure in a sandwich keyboard formed with a printed circuit board having many electrical conductive paths thereon, with the actuator members being integrally formed with a connecting bus. The device is provided with a number of bendable fingers for making contact with any desired conductive path lying beneath the fingers thereby permitting the device to serve as a "jumper connector" without adding wire jumpers to the back of the printed circuit board. The actuator member is constructed to have self cleaning contact surfaces. A plurality of such actuators is preferably formed of a single strip of thin sheet metal.
