Micro switches are pretty basic in terms of their functionality. However, there are a few key terms you should know if you’re looking at buying or installing a micro switch.
NC – NC stands for normally closed, which means that the switch is connected to a closed circuit which opens once the switch is activated.
NO – NO stands for normally open, which means that the switch is connected to an open circuit which closes once the switch is activated.
Operating Force – This is the amount of force needed to activate the switch. The switch will not activate if a force less than this amount is applied to the switch. In our switches this is measured in grams.
Free Position – How the switch sits when no force is being applied.
