The Acer switch is a spring-over-membrane switch from Acer. Acer switches are clicky and tactile and use Alps mount keycaps. They are relatively similar in appearance to Alps CM switches, but the clear Acer branding prevents misidentification.
Acer switches are a hybrid of Alps CM and membrane rubber dome keyboards. The rubber dome is replaced with an Alps mechanism, and the switch is open at the bottom to allow a hinged plastic part to press on the membrane. The tactile feel and audible click are provided by a folded leaf spring identical to Alps switches. Unlike with Alps switches, the leaf spring cannot be directly removed, as a small plastic lug on the slider keeps the spring in place.
While the switches are discrete, they are mounted directly into the case itself, instead of into a steel plate.
The switch has two variants: one with a white slider and one with a black slider:
The two variants are considered to be identical, differing solely in pigmentation.
Opinion on the feel of Acer switches varies, but the overall consensus is negative. The force curve is balky, similar to XM Alps clones, and to some the membrane feel is too obvious.
Acer keyboards can be used to source keycaps for Alps keyboards as they share the same mount.
