The previous switch review from a month ago was for the JWK Unlubed Linear switches from 1Up Keyboards, which is worth mentioning because this review is for their sibling switches, the JWK Unlubed Silent Linear switches, naturally also sold by 1Up Keyboards. Like the normal linear version and the TECSEE Purple Panda tactile switches, 1Up provided a discount to support these switch reviews. The critical difference between them is the presence of silicone dampeners on the stem, so both the down stroke and up stroke involve softer plastic-on-silicone impacts rather than hard plastic-on-plastic impacts. These are priced at $0.75 a switch, compared to the $0.60 of the non-silent versions.
