Tactile Metal Domes Suppliers in Singapore
2
Metal domes add a tactile feel to products in a
variety of industries which includes automotive
switches, medical instrumentation, aerospace
cockpit panels, wireless handheld devices, smart
card applications, membrane panels, marine
controls, security military devices, mobile
communications and anywhere else where
low-profile momentary switch is required.

Polytech works directly with customers worldwide
and our goal is to provide the best customer
service and industry expertise to make our
customers project a success. Every project is
different and Polytech has the in-house
capabilities to create custom domes for your
product.

Whether you require a minor adjustment to an
existing tactile dome e.g. tactile trip force,
snap action feel (tactile ratio),or a completely
new design concept, Polytech has the expertise to
accommodate. Our tactile domes are momentary
switch contacts that, when used in conjunction
with a printed circuit board, flex circuit or
membrane, which normally becomes open tactile
switches.
5
Tactile domes are placed onto the substrate with
pressure sensitive adhesive tape array or
captured in a membrane-type pocket design. The
movement of air is called venting and is
important so that the dome functions properly.
Lack of venting can cause unfavourable effects on
the feel and function of the switch.
6
Mostly venting is not absolutely necessary for
every application but it is desirable in almost
all applications. When the dome is depressed,
then air is trapped underneath it and it is
recommended that a vent channel be present to
avoid compressing the air under the dome when
actuated.
7
The venting of the dome can be achieved a number
of different ways. Vent channel can go from dome
to dome via a spacer layer and dome arrays can be
top vented through the polyester material. Vent
channel can go through the board and the absence
of proper venting will lead the dome to result in
significant loss of tactile response.
8
In addition to our wide range of standard tactile
metal domes, we also offer custom metal domes
which your application may need. Whether you need
a custom size, shape, actuation force, etc., we
will work within your design constraints to
provide the exact metal dome for your application.

Do you have competitors and you arent sure if we
have already made that particular metal dome?
Please use our cross-reference search engine to
find out if we have already manufactured an exact
match for your search, chances are good that we
have something very close that we can recommend
and if not, well be happy to create the dome for
you.

A typical characteristic of metal dome switches
are that, the life decreases as the actuation
force increases in relation to the domes size.
The result is that design engineers have often
had to sacrifice actuation force in order to
achieve the desired cycle life.
