IEVT/Tipro Series TC
Contents
Overview
“Tipka s hermetičnim kontaktnikom Serije TC” (Series TC hermetic contact keyswitch) is a series of keyboard switches originated at IEVT and continued by Tipro until the latter organisation discontinued them in favour of Cherry MX. Series TC is presumably a reed switch series. The switch body is fairly tall, suggesting that the reed capsule is mounted vertically within the switch.
Series TC switches accept Series Y keycaps.
Models
The following models are listed in the IEVT/Tipro switches and keycaps brochure. A suffix of “/10” (e.g. TC 1A/10) denotes a 10° keystem, which results in a switch with an overall 1 mm taller plunger to provide clearance for the angled keycap.
The details below carry the caveat that they may be mistranslated or misunderstood.
