5mm Mercury switch tilt angle sensor Unidirectional electric induction switch pack of 5pcs
This mercury sensor has one or more sets of electrical contacts in a sealed glass envelope that contains a small quantity of mercury. The envelope may also contain hydrogen at pressure, an inert gas, or a vacuum. Gravity constantly pulls the drop of mercury to the lowest point in the envelope. When the switch is tilted in the appropriate direction, the mercury touches a set of contacts, thus completing an electrical circuit. Tilting the switch in the opposite direction moves the mercury away from that set of contacts, breaking that circuit.
This is the pack of 5 pieces of 5mm Mercury switch tilt angle sensor Unidirectional electric induction switch
- The contacts are enclosed.
- The switches are quiet, as no contacts abruptly snap together.
- The mass of the moving mercury drop provides an over-center effect to avoid chattering as the switch tilts.
