But I took a picture from the rearside of the panel pcb; and appearently these switches are in fact soldered parts; they are not rubber stamp on printed pcb contact areas as we know it from keyboards. Then I went to my workshop and found immediately a momentary switch, which would fit the pcb. I can't tell you the brand or type, but it exists. It should not be too diffcult to mount / glue the switch caps on it. Maybe a brave soul recognizes the type of switches, the distance of the solder points is appearently 0.2 inches. pictures are here: http://www.florian-anwander.de/pearl_sc40/pearl_sc40_panelpcb.jpg http://www.florian-anwander.de/pearl_sc40/pearl_sc40_switchreplacement1.jpg http://www.florian-anwander.de/pearl_sc40/pearl_sc40_switchreplacement2.jpg Florian
