ED Domes and EDM Domes

Construction

EDM

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.

PC pins or tabs

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.
