Abstract
A preselection counter having a switch-off counter which is adapted to actuate a desired function when a quantity of this function determined by a preset value has been reached includes presettable indicating means having number rollers adapted to have the preset value set therein and to retain this setting through repeated cycles of operation of the switch-off counter. The presettable indicating means enable continuous display of the preset value during operation of the counter with the preset value being transferred from the number rollers of the switch-off counter by a sensing wheel mechanism which is operatively interposed therebetween and which may be repeatedly reset to the preset value on the preset counter after each cycle of operation of the switch-off counter without requiring changes in the preset value in the presettable indicating means.
