Description
Technical Field
The invention relates to the field of switch control, in particular to a position switch.
Background
In the prior art, switch control is used in various situations, such as water level control, and non-liquid level control (namely pressure, gravity, push-pull force, rotation moment and the like), and the switch control is realized through different positions. Taking liquid level control as an example, the floating ball liquid level controller is designed by utilizing the principles of gravity and buoyancy. The three-core cable mainly comprises a buoy body, a high-capacity micro switch arranged in the buoy body, a driving mechanism capable of enabling the switch to be in an on-off state, and a three-core cable connected with the switch. When the floating ball rises or falls to a certain angle with the horizontal under the action of the liquid buoyancy force along with the liquid level, the driving mechanism in the floating ball drives the high-capacity micro switch, so that a switch signal is output.
However, when the floating ball floats at will, the switch is easy to be out of work or misoperation, and the sensitivity is reduced.
