360° of ball access provides smooth travel of the ball downward resulting in longer life and better reliability. The shorter length of the body helps the installer by eliminating the need for a long, deep hole to allow for a switch housing. The collar is flanged to insure reliability with positioning and the positive retention when the switch is installed. GRI’s creation of the new short roller ball style switch uses a magnetic reed with a rolling ball to control the magnet. The ball plunger can be actuated from any direction. Our improved short roller ball switch is actuated when the ball rolls into the switch rather than simply being forced into the housing.
