Pcb Button Pad

Each button has a conductive circle backing so that a switch can be created with exposed pcb traces.

Pcb button pad. Now the patten can fit several types of pushbuttons or a molex kk connector for off board buttons. First the rgb led that the pcb was designed for is no longer available. Install 6mm tactile buttons. Each led and button is brought out to the side connectors.

This a simple breakout board for the button pads. A 4720 qty available. The button pad pcb design dates from around 2008 relatively early in sfe history. Faster and more reliable soldering of through hole parts.

The cap pads are small disks 150 mils 3 8 mm in diameter and otherwise surrounded by ground on the top layer. The connectors are soldered to the back side of the pcb. 5mm leds are too big so stick with 3mm here. Once installed place your hand over the buttons and bend each of the leads inward so they bite onto the pcb this will help hold them in place.

The microcontroller is a pic 16lf1786. Single sided pcb pads are ideal for 4 leg domes whereas the trace is not compromised when the dome is actuated. By default most pcb layout programs use 0 056 inch diameter pads around the common 0 029 inch diameter holes. Button force is between 190 and 210grams activation force nice tactile feel like on your tv remote.

If you need the leds pcb or black bezel please see below. We recommend trimming the connector leads on the button side as short as possible to reduce the deflection of the pad. Double sided contact pad suitable for all domes except oblong double sided pcb pads can be used for all snaptron dome styles except oblong and dual action dt series. On the bottom of each button is a conductive pad ring which can close a properly design contact underneath.

Insert each button into the through hole spots on the gamepad pcb. This product is for the white rubber only. We have an eaglecad library which has objects for the buttons and optional leds so you can use them in your next pcb design. Let s clarify a few points.

It and all the other parts that aren t for directly interfacing with the user are mounted on the bottom of this two layer board. 16 button pad can be split up into four 4 button pads.
