Do not attempt to screw the Bremas switch handle into the mounting shaft of the Bremas control box without following these steps. You will damage the Bremas switch handle.
Step 1: Remove the mounting screw from the Bremas switch handle before installing it on the drum switch.
Step 2: Install the Bremas switch handle on the Bremas drum switch mounting shaft. The handle should be flush to the face of the control box. If the handle will not fit flush, slightly bend the expansion tabs to fit flush on the drum switch.
Step 2: Insert the mounting screw into the mounting hole on the Bremas switch handle.
Step 3: Tighten the mounting screw. Be careful not to overtighten the screw.
Step 4: Operate the switch back and forth to test the handle is secured to the control box.
