Switch for medical or surgical appliances has data processor programmed to store instantaneous position of foot on mat as output signal, selects switching region and generates switching signal if foot is in switching region of sensor

摘要

The switch has a flat foot mat (2) with sensors (3) distributed over its surface that produce an electrical signal corresponding to the position of the operator's foot (4) on the mat when the foot is near the respective sensor and a data processor (6) programmed to store the instantaneous position of the foot on the mat as an output signal when activated by an activating signal, select at least one switching region (8-12) with a defined position relative to a starting position and generate a switching signal if the foot is in the switching region of a sensor. Independent claims are also included for (1) an arrangement for implementing the inventive method (2) a method of implementing the inventive method.
