What actuation force options are available for MEC switches, and how can they be customized?

Explore questions related to actuation force, including custom options and how actuation force impacts switch performance. MEC offers a variety of force options to ensure the perfect tactile response for any project.

› Can MEC build other actuation forces than the standard actuation forces?

We can provide switches with custom force ranging from 2.0N up to 10N.

› Is it possible to have a higher operating force than the normal 3.5N (3 series) and 2.0N (5 series) for a quiet switch?

Yes, it is possible to produce a quiet Multimec switch with an operating force higher than the standard 2.0N. The minimum order quantity for these special switches is typically 20K. Please consult MEC with your request.

› Can I have the switch with 1N actuation force?

If we reduce the operating force too much, there’s a risk that friction, rather than the metal dome, controls the actuation. For this reason, the lowest actuation force we offer is 2N ±0.2N.

› What is the actuator travel distance?

We guarantee contact is established after 1 mm, but due to tolerances in the metal dome alloy, this cannot be specified 100%. In practice, contact is often established before 1 mm.

› Can contact be established before 1 mm travel?

Yes, in practice, contact is established before 1 mm travel, but MEC guarantees contact is fully established at 1 mm.

› What is the tolerance for the 1 mm travel?

The tolerance for the travel distance is 1.1 mm ± 0.1 mm.

› If a mechanical stop is built on the switch, where should the stop be placed?

The mechanical stop should be placed after 1 mm of travel.
