In the weakest axis, 20G against vibration, 40G against shock. Its movable contact, which is small, compared to that of the conventional reedswitches, and the spring-assisted return industrial presses it gainst the glass tube (backstop mechanism) to make it strong against vibration and shock even when non-energized.

Bestact is a hermetically sealed contact in a glass tube that can be used in circuits up to 240VAC or 240VDC. This means it remains entirely unaffected by external factors such as gas, dust, water and oil, and maintains extrmely high reliability and fucntion over a long period of time.
