Haimu Heartbeat Silent Linear Switch

After lubing Haimu Heartbeat Silent Linear Switches with Krytox GPL 205G0, and foam modding, my board is completely silent. I needed a truly silent switch & board for my work so people wouldn’t hear me clicking away over Zoom meetings. Would recommend Haimu Heartbeat Silent Linear Switches to anyone like myself that needs complete silence when typing.

Truly silent!

The best silent switch I’ve ever tried without needing further modifications. 10/10

Great silent linear with adequate factory lube

I love these switches in the stock configuration. I in fact preferred them over the very popular (and expensive) Gazzew Boba Gum silent linear switches. I preferred stock heartbeats even over a hand lubed Boba Gum with GPL205 G0 and 105 on the spring. The heartbeats are smooth with little to no scratch, and the sound is nice and quiet. I prefer heavier springs so the 65g spring felt right at home for me.

I have a NovelKeys NK87 entry edition with these switches installed and love it for a quiet mechanical keyboard to have at the office. Doesn't bother my coworkers and feels just as satisfying to type on. I've come to like the type of sound silent switches produce too.

For those who care about RGB compatibility, below is a picture of that keyboard but with transparent polycarbonate keycaps. You can see that RGB is no issue for these switches although you can see some red tint to it from the switch housing color.
