ED
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 3.0 mm
(0.118) 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.
EDM
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 profile applications
needing increased tactile response
and high performance specifications.
Applications range from aircraft instru-
ment 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).
