under the microgravity condition, the gravity action of the left weight (11) and the right weight (4) disappears, the pressure of the left friction plate (12.1) and the right friction plate (2.1) clamped on the Morse cones (16.1) at the two sides of the inner sliding sleeve (16) disappears, the friction force generated by the pressure also disappears, the static balance state of the inner sliding sleeve (16) is broken, the inner sliding sleeve (16) rapidly bounces upwards under the elastic action of the main spring (13), the copper plate (15) at the top end of the inner sliding sleeve (16) is in contact with the left electrode (9.1) and the right electrode (6.1), and the circuit of the left plug (9) and the circuit of the right plug (6) are conducted.
4. A microgravity triggered circuit switch as recited in claim 1, wherein: the reset rod (8) is arranged at the center of the top end of the shell (1) to form a moving pair, a reset spring (7) is arranged between the top end of the shell (1) and the upper end of the reset rod (8), and the reset rod (8) is positioned at the uppermost end of the stroke of the reset spring (7) under the elastic force action;
after the microgravity experiment is completed, a circuit switch needs to be disconnected, even if the inner sliding sleeve (16) located at the upper end position is reset to the initial state of the lower end position, the reset rod (8) only needs to be pressed downwards under the normal gravity condition, so that the lower end of the reset rod (8) pushes the inner sliding sleeve (16) to move downwards to the initial position, and under the clamping of the left friction plate (12.1) and the right friction plate (2.1), the inner sliding sleeve (16) is located at the initial position and reaches the static balance state.
