Pressure switch (ring pressure). Closes contact as long as it is pressed.
The switch is mounted on a solid base plate with safety bushings.
Max. breaking current: 3 A.
Base plate: 120 x 90 mm.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
