FIELD: electric engineering. SUBSTANCE: device has contact element 6 which is located above resistive element 2 on cover 5 inside pliable cap 3. Working chamber 10 is connected to return chamber 11 through channels 9. Return chamber 11 is connected to air through holes. This results in possibility to prevent over-pressure in chamber 10 when cap 5 is pressed in order to decrease resistor resistance. Another claim of invention describes device design in which chamber 11 is sealed against air. Yet another claim of invention describes device design in which non-sealed chamber 11 has sealed pliable wall 14 which prevents over-pressure in chamber 10. EFFECT: increased functional capabilities. 3 cl, 1 dwg |
