The switch is mounted on a solid base plate with safety bushings.
Max. breaking current: 3 A.
Base plate: 120 x 90 mm.
Designed to allow the use of a force sensor as a balance.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
