DUROCK Tactile T1 Switches have a smooth round bump then smooth snap after the bump. The bump is very noticeable, and it gives you a lot of feedback upon actuation - responsive to the touch. OEM special design which is close to original Holy panda but still with its own unique tactile feelings. The top housing is Polycarbonate, and the lower housing is Nylon PA. PERHATIAN : * PIN SWITCH TIDAK LURUS / BENGKONG ADALAH HAL YANG WAJAR (SELAMA TIDAK PATAH), PASTIKAN LURUSKAN PIN SEBELUM DIPASANG DI KEYBOARD. KAMI SUDAH JUAL SWITCH SANGAT BANYAK, DAN SEMUA SWITCH DI MKID BERASAL LANGSUNG DARI PABRIK / MANUFACTURER YANG BERSANGKUTAN. KARENA KITA ORDER PARTAI BESAR, MENEKAN HARGA JUAL, SUPAYA BISA MENIKMATI SWITCH DENGAN HARGA TERJANGKAU DAN SEMESTINYA.
