NEW PRODUCTS – Membrane 1×4 Keypad and LED Keypad + Extras
NEW PRODUCT – Membrane 1×4 Keypad + Extras – Punch in your secret key into this numeric membrane keypad. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required – just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. It’s a simple keypad but that’s why we like it.
We include a 5-pin extra-long header strip so you can plug this into a breadboard with ease.
Technical Details
Weight: 2.83g
Keypad dimensions: 69.14mm / 2.72″ x 20.07mm / 0.79″
Length of cable + connector: 87.31mm / 3.43″ x 14.28mm / 0.56″
NEW PRODUCT – Membrane LED Keypad + extras – This membrane keypad has a single key, but it does have an embedded surface-mount red LED installed. The flex cable is also extra-long, so we can think of a lot of wearable and portable projects that would use this sort of switch and have an LED as feedback (say, to indicate that an action is occuring or the power is on). Since the keypad is soft plastic, it can be sewn with needle and thread.
The back of the pad has a removable paper cover that protects an adhesive backing. You can see how the pins correspond to the LED anode/cathode and button by looking at the photos above.
We include a 3-pin extra-long header strip so you can plug this into a breadboard with ease.
