ED Domes and EDM Domes

ED, the disc contact is a momentary tact switch with short travel and good tactile feedback. Direct mounting on a printed circuit board is possible.

In that case, the dome must be actuated by a soft actuator of mm minimum diameter. The ED dome is available in various types of modules and is the main component of several switches presented in this catalog.

Self-cleaning system The contact is made on at least 3 points of the lower diaphragm, these 3 points of contacts are always different at each new switch action. During the switching movement, the upper disc slides on the lower diaphragm, ensuring the contact’s self-cleaning.

The EDM is available in 4 versions EDM 450 AU EDM 650 AU EDM 450 AG EDM 650 AG

The EDM Multi Dome Series was developed for low applications needing increased tactile response and high performance

Applications range from aircraft instrument panels to radio keypads. This high performance dome switch combines our reliable ED contact system with added tactile domes for forces of 4.5N 450 grams and 6.5N 650 grams .
