Abstract
A circuit controls a height-adjustable table. A current load acts on the table plate and is measured by a force-sensitive sensor and serves as control signal of a control according to the invention. Derived from this signal, a collision of the electrically height-adjustable table with fixed objects is recognized. Control signals are also detected, which are inputted by an operator of the table in the form of applications of force onto the table plate. Here, the table or respectively the control device is situated in a state of rest until the user of the table exerts a brief force impulse onto the table plate, i.e. presses once onto the table plate. Thereafter, the control changes from a state of rest into an operating state and waits for control inputs. When the user now presses from above onto the table plate, the latter moves electrically downwards.
