Multimec™ 3C

Multimec™ 3C

New product

Simplicity and reliability makes the Multimec™ 3C an excellent switch for build-in and over-mould solutions. In addition, the switch is great for overlay as it can still function even if the overlay breaks and an upgrade can be done by changing the overlay and not the PCB, which is very cost-effective.
