A scissor mount for a large, multi-contact key of a keyboard, prevents key tilt upon off-center actuation of the key. Such keys are often lifted from immovable portions of keyboards and then remounted in order to change contacts that are activated by the keys. When this is improperly carried out, guide slits can become deformed and the entire apparatus becomes unusable. In the arrangement of this invention, scissor arms (7), whose guide pins (8) ride in guide slots (10) of fixed keyboard parts, are formed as springs, with ends of the guide pins being inclined for engaging and sliding over guide-slot walls during installation so that the scissor arms can spring inwardly until the guide pins snap into the guide slots. With this arrangement deformation of guide-slot walls is avoided and an easier mounting is made possible.
