The housing is made of black synthetic material and the electrical parts are made of a copper alloy with a tin coating. This phone jack is available from various manufacturers in the same mechanical and technical construction. An exception is the manufacturer HOSIDEN using a wider housing. The electrical connection has the same structure.Praktikal tip:These phone jack is firmly soldered to a circuit board. For replacing craftsmanship and experience in soldering is required.

1 pcs. slide potentiometer with 30mm travel and 15mm Lever. Suitable forRoland HP-136Roland HP-236Roland HP-237Attention: Lever - Slide pin must be shortende around 5 mmThis volume control with the labelling EWANNBX10B14 is no longer available from manufacturer Panasonic because the pot is not longer produced by them. We offer here a slide potentiometer with the same technical performance as the original part.Electrical properties:The stereo nominal resistance has 10 k? (Kilo-Ohm), the electric resistance gradient is linear. The potentiometer is construed for a power of 0,06 Watt.Appearance (technical characterisation):This slide potentiometer has been built in in the past in many instruments and audio equipements. The particular embodiment of this potentiometer is the arrangement of the solder contact pins, which today are no longer usual. In total eight solder contact pins are laterally ordered to a group of four pins at the top and the end of the slide potentiometer. On both sides the solder pins are staggered in reverse order. Because of this arrangement the volume control fits only in a specific mounting position. The slide potentiometer has a travel of 30 mm. Its metallic casing measures 45 x 8 mm, the height without lever is 7 mm. The lever is made of black plastic and ends in corner radius. Its height is 15 mm, the breadth is 5 mm and its depth is 2 mm. The eight solder contact pins are 0,8 mm wide (one of them) and they are arranged in a distance of 3 mm. The bented pins are necessary for the electrical function.In medium range of the casing the metallic edge-socket connector is mounted. By these connectors the slide potentiometer will be fixed mechanically.Useful hint:The volume control is soldered on the circuit board. You should have mechanical skills and experience in soldering to replace it. 

Single-pole push switch in the switch design - OFF with solder pins for PCB mounting suitable for modelsKorg Korg Part Number:The power switch corresponds to the ALPS switches SDDLD12200 TV3. This is no longer manufactured by ALPS.Termination Solder pinMounting PCBVDE-tested Supplied without capMechanical Description:The housing of the switch is made of nylon 66. The switch is provided for PCB mounting. Therefor are tow solder pins as Snap-In pins in the front. The spacing of the snap in pins is 16 mm. The housing cut job of performing the switching element should be 4x4 mm. The switch itself has a width of 10 mm, a length of 27 mm and a height of 17.90 mm. The protruding switching element has a length of 18 mm. Electrical properties:The electrical components are made of copper with a silver or tin plating. The electrical connection is made with solder connections for cable assembly. The length of the terminals is 4.2 mm and a width of 3 mm.The electrical load is 4 A at 250 VAC.Knowledge in soldering is required for switch replacement.
