Abstract
A catch for two objects moveable in relation to one another, in particular a door catch, includes a cylinder, which is operatively connected to a first object, a friction surface carrier, which is operatively connected to a second object, a friction element for creating a frictional grip between the cylinder and the friction surface carrier through an energy input. The friction element being connected to an electrical voltage supply device, wherein a change in the volume of the friction element, which constitutes an actuating movement of the friction element in relation to the friction surface, occurs as a function of the voltage applied to the friction element.
