ABSTRACT:
A calculator includes a shell defining two slots. The calculator uses a switch and a power supply. The switch includes two tubular portions projecting therefrom and being slidably received in the slots so that the switch can be moved between ON and OFF positions. The power supply uses a plate defining two apertures. Two screws are inserted through the apertures and secured in the tubular portions, thus joining the switch with the plate for retaining the switch on the shell. A casing is received in the shell so that the plate is enclosed in the casing. At least one container is formed on the casing and defining an inlet through which aqueous solution of salt can be filled into the container and an outlet through which the casing is in fluid communication with the container. At least one pair of positive and negative electrodes is attached to the plate. At least one absorber is received in the casing. At least one filament is inserted through the outlet for inducing the aqueous solution of salt from the container to absorber. In the OFF position, the electrodes do not contact the absorber so as to prevent any chemical reaction between the electrodes and the aqueous solution of salt so as not to generate a current. In the ON position, the electrodes contact the absorber so as to allow a chemical reaction between the electrodes and the aqueous solution of salt to occur so as to generate a current.
