It has not been tested on other models. Longitudinal section (section) of one rubber button from remote control type "Horizon": 5 1 ┌───┐ 1 ──────── │ │ /──────── ──────── 4▄▄▄▄▄▄▄▄▄4 / ──────── 2─┘ : : └─/2/ : : / │ 6 6 │ └───────────┘ 3 Designations in the figure: ======================= 1 - a layer of rubber that “fastens” all the buttons into a single block. 2 - corrugated rubber for a springy (tactile) effect. 3 - the surface of the button on which you press with your finger. :) 4 - layer of conductive rubber. 5 - bracket made of thin tinned wire. 6 - holes (two) for the bracket, made with a needle. Holes are made in a layer of thin conductive rubbersewing needle to a depth of approximately 2.5-3 mm, moving away from the edges The conductive “heel” is about 0.5-1 mm. No need to pierce button through! We make the bracket using tweezers from thin (0.2-0.4 mm) tinned wires I used strands from stranded wire. It's necessary accurately maintain the distance between the ends of the bracket, depending on depends on the distance between pre-made holes in the rubber buttons. For reliability/durability, it is desirable that the bracket entered the rubber of the button to a depth of at least 2.5-3 mm. Bracket installed in prepared holes using tweezers. . ==== end of file "RCbutton.C" ================== Best regards, Felix. [I.ZX] -+- Lara_Croft_v4.40 + Origin: Live and learn!
