Product Features
Resolution:
A standard operator can be depressed enough to open a normally closed contact without latching into the depressed position (also referred to as teasing the contact).
The trigger action units have a spring loaded mechanism that causes the operator to pull fully into the depressed position after a certain actuation distance confirming the operator has been switched.
