ABSTRACT:
The key provided for manual operations of the functioning of an electrical scale is constituted by an elongated bar which rests on two control switches. The control switches are connected to the control circuit of the scale so that activation of either one will result in the furnishing of the same control signal to the control circuit. The location of force applied to the activating member is immaterial, since no matter where the bar is touched, one or both of the switches will be depressed. This permits the operator to control the functioning of the scale without moving his eyes from the display.
