The heavy duty (0.032 in thick) stainless steel construction of this lever ensures long lasting reliable operation. A micro switch is used to provide both Normally Open (NO) and Normally Closed (NC) contacts that sense lever activation and release respectively.

The force required to move the bar is factory calibrated to be less than 10 gm and is field adjustable via counterbalance washers located on the back. This is preferred over spring systems that can change over time or hang up on the moving lever. Movement required to activate the lever switch is 3 mm.
