Patent number: 5874700Abstract: This invention relates to a switch mat with key switches. In previously disclosed switch mats, switch chambers located under dome-shaped key caps were jointly vented. This affected key operation, and allowed soiling by dust and moisture. Here, each switch chamber has a ventilating channel with a filter layer that is permeable to air, for venting to and from the outside. In this design, the filter layer is formed by a filter matting that is dust and moisture-repellent. Because each switch chamber is separately vented to and from the outside, there is no mutual influence on operating forces of the key switches.Type: GrantFiled: March 5, 1997Date of Patent: February 23, 1999Assignee: Preh-Werke GmbH & Co. KGInventor: Gerhard Hochgesang

Patent number: 5747758Abstract: 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.Type: GrantFiled: September 27, 1996Date of Patent: May 5, 1998Assignee: Preh-Werke GmbH & Co.

Patent number: 5532444Abstract: A push button switch, particularly a power supply switch, has contacts (4, 5) attached to a housing and a movable contact bridge (8) which is moved by means of a spring plunger (10'). A spring switching mechanism (26) transmits force between the spring plunger (10') and a manually-actuated switch actuator (22'). The switch actuator (22') is alternately latched and unlatched by a locking linkage (27, 28) which alternately holds the switch actuator in "switched-on" and "switched-off" positions when the switch actuator is repeatedly pushed. Additionally, a switching rocker (51) is provided between the switch actuator (22') and the spring plunger (10') to improve switching action. The switching rocker (51), at the beginning of "switching-on" and "switching-off" operations, forcibly carries the spring plunger (10') in its respective switching direction through a partial path of its contact stroke (H).Type: GrantFiled: August 7, 1995Date of Patent: July 2, 1996Assignee: Preh-Werke GmbH & Co., KGInventors: Herbert Bonrath, Gerhard Hochgesang, Ulrich Bruggemann, Hans-Karl Heil
