GRIaposaposs Roller Ball Switch is a unique application of a magnetic reed combined into a single package, mechanical plunger action and the reliability of a hermetically sealed switch.
The ball plunger can be activated from any direction within 360 degrees, using a sliding motion such as that produced by the opening or closing of a door or window into its frame.
But they also have been used very effectively as an interior trap device by mounting on a flat surface, such as a display table, and placing the protected object directly on the switch to conceal and actuate the roller ball.
