Abstract

270,980. Munthesen, M. Dec. 4, 1926. Press - button switches; actuating; cases. - A pressbutton switch is enclosed in a fluid-tight casing one wall of which takes the form of a diaphragm 10 and mechanism arranged between the diaphragm and the press-button 4 serves to convert a small movement of the diaphragm, when the latter is depressed by a press-button 12, into a relatively large movement of the button 4. The amplifying mechanism may comprise two levers 14, 16 arranged e.g. as shown, or the diaphragm may operate a toothed rack which engages a gear wheel, the latter having fixed to it a smaller gear wheel which engages a rack on the button 4.
