Level alarm switches can optionally type single floats or multiple floats, the floats are sealed with stainless steel or engineering plastic. Similar to contact, it is possible to optionally 1 or more closed contactes in stainless steel or plastic plants. The user can mount the float and contact in the appropriate position, and limit the range of floats when the level of liquid increases or decreases.
When the permanent magnet hits the point of mounting the chicken tongue contact position, it acts as a magnet to switch the state to ON or OFF, from which the switch gives the output signal for monitoring or control.
