OVERVIEW
H20PS series pressure switch is a miniature pressure switch.It controls the circuit open or close on pressure of controlled medium increase or decrease. It is wdiely uded in refrigeration system, which require to adjust the medium pressure to protect system.
WORKING PRINCIPLE
the working principle of H20PS sereis pressure switch is :when the pressure of the controlled medinum rise to a predetermined value, the mentalflip disk will flip and drive s set electrical contacts by means of a transfer pin. when the pressure of the controlled medium drops below another predetermined value, the snap disk will flip to the original state, to make the switch function is realized.
