An electromechanical joining module for applying a linear force to a joining element, includes a stator, which represents the stationary part of the joining module, a tappet, which can be linearly extended out of the stator and which has an outer tappet end, and a force transducer for detecting forces that are applied to the joining element during the operation of the tappet end. A display is positioned in association with the function keys and provides both a message section for displaying a text or pictorial message in association with a current mode of operation and an icon section for displaying an icon in association with each of the function keys wherein each icon symbolizes a non-data entry function selectable by actuation of the associated key in the current mode. A space is provided through which the curtain air bag deploys. The connection tube is adjustable to be connected with a curved rod. Effective pixel density is increased to compensate for attenuated output in dim areas. Two squeeze-levers are provided for actuating the grinder, with a lock for selectively disabling one of them so that only one condiment is dispensed at a time.
