A pressure switch is a type of switch that switches off an electrical contact point when a particular amount of force is reached upon input. The pressure switch is designed in such a way that it makes contact on either the pressure rising or falling. A different type of pressure switch is able to detect mechanical force. For e.g. – A pressure sensitive mat that automatically opens doors in office complexes. A pressure switch for the purpose of sensing liquid pressure comprises bellows, capsules, Bourdon tubes, piston elements or diaphragms that displace proportionately in relation to the pressure applied. The resultant motion is either directly applied or through the help of amplifying levers to a switch contact set. As the pressure can be slow acting and the contacts should ideally operate quickly, an over-centre mechanism like a mini snap-action switch is deployed to ensure rapid contact operation. A certain type of sensitive pressure switch available in the global pressure s...
