Switches
Description
Designers of compact devices with high functionality requirements
– such as consumer devices and medical devices – need switches
that have a low profile and low actuation force. That’s where the
HDT Series of micro mini surface mount detect switches from
C&K come in. They’re designed to be quality, long-lasting switches
that only allow a maximum actuation force of 35g – and are
available with either top or side actuation, making it easy to
incorporate the switch into your device design.
