More
surface area means better button conductivity.
The Pad Mate's® conductive
contacts are super-sized to 7 mm in diameter to match the corresponding 7mm
contacts on the circuit board. This delivers a whopping 206% more surface
area than the 4mm contacts on the original Panasonic keypad!
|
* It's a geometric fact: Surface area of a circle grows
exponentially as diameter increases.
The
diameter of the Perma-Pad® contact is 75% bigger than the
original's, but that translates into 206% more surface
area. Here's why:
Original Panasonic button is 4mm in diameter. Surface
area =
pr2,
or 3.14 x 22 = 12.56 mm2. Barclay
Perma-Pad®
button is 7mm in diameter.
Surface area = 3.14 x 3.52 = 38.46 mm2.
Increase in size is: (38.36 / 12.56) - 1% = 2.06 =
206%. |
No other keypad or membrane on the market for
Panasonic KX-TG handsets has bigger button contacts!
