Jelco JKS-91 is an integrated dome discrete key switch which appears to be modelled after the Alps SKCC series. Unlike the Alps integrated dome series, the JKS-91 uses two vertically-mounted contacts (which extend down as the legs) with a rubber dome that fits inside a vertically-mounted cartridge similar to a switchplate. The slider's vertical travel is converted to horizontal motion by way of an actuator leaf very similar to those in mechanical switchplates.
