A replacement button board for 2000-2006 Honda Insight instrument clusters. The frequently-used stock buttons tend to break and stop working, making it no longer possible to use the trip meters or reset the maintenance light once it comes on.
You need two boards per cluster, and OSHPark sells them in threes, so you’re golden. You’ll have to file off the tabs left by the manufacturing process to ensure a proper fit in the cluster. Make sure you get standard board thickness (1.6mm), not 0.8mm!
This board should fit any 6.2x6.2mm j-lead tactile switch, but is intended specifically for C&K’s KSC4 line. The CTS 222K line is also directly compatible.
I’m using the KSC403J50SHLFG because it meets the below requirements and was in stock at the time of submitting this. Less ideal but acceptable alternatives are C&K KSC401J50SHLFS or CTS 222KJVAAR.
You’ll need to take the wire harness off the stock boards. The pins are close enough together that this is easy to do by adding a bunch of solder and heating all three pins with your iron at once, then pulling the harness out.
Tact requirements/nice-to-haves:
Top of the actuator must be no more than 6.5mm off the board (stock buttons are 5mm tall, for reference)
For longest life, the button should be dust/waterproof (IP65-68)
The tact should ideally have a silicone actuator, so when you’re pressing the buttons, you’re not accidentally putting undue stress on them. It also feels nicer.
Actuation force should be around 1.6N/160gf (a pretty standard value), this feels like a bit more than stock. I tested a 2.25N button and it was a little too much, in my opinion.
The tact should have a minimum current less than or equal to 500uA (the cluster uses a 10k pullup to 5V). This isn’t critical, but you will technically get fewer cycles out of the button if you have less than the minimum current going through it since oxidation can build up. This shouldn’t realistically be an issue - if your tact is rated for 1 million cycles and you get 10% of that, you could press the button 10 times a day and it’d still last almost 30 years.
