I had no issues with this 'T' configuration of buttons. Buttons make solid contact and are easy enough to press. Ribbon cable is flexible enough to easily route as necessary.

Purchased these multiple times, had an issue with some sticky buttons in which the seller quickly made right and moving forward I will be purchasing these to build my devices as the quality and performance is exactly as expected. Great customer service after the sale!

I like the positive click on these and the measurements I see on contact resistance (less than .5 ohms, the limit of my meter). Labeled as 1, 2, 3 & 4, this makes for a wide variety of applications. The ribbon cable length is good, and the 0.1" on-center connector is an industry standard, making for very easy connections to whatever projects you want to use these on. Coming in a pack of three is good for having a spare or two on hand for your project in case you damage the keypad in the field. Nice units.
