The pressure switch is a high and low pressure £&≠protection control, ste♣≠¥am service and power station  ↑widely used in household, commercial and au✔✔tomotive refrigeration systems. It can a±×λ₹lso be used for high and low pressure protection ↕≥control of various equπ₽₩ipment tools. However, i∏ n the selection of the ÷‍←pressure switch, the following points shoulβ÷d be noted: 1. The necessity of​↓ explosion-proof: The exploα¥Ω÷sion-proof form is divided into explosion-pr>¥₽★oof type and intrinsic safety type, and most o≥✘f Nagano products are explosion-proof ty± pe. 2. Do you need to bring instructions: acco£ ↓σrding to customer instructions. 3. Numb↔≈δer of contacts: one contact (one ou₽¶tput) or two contacts (two outputs). 4. Determina>‌γεtion of set value and pressu¶"re range: The recommended settiδ→φεng range is between 30% and 65"ε≤×% of the pressure range, and the se<σ•‌ttable range is between 15% and 90% ✘↑×of the pressure range. 5. Is there a pulsation•↓γ: If the pressure is pulsating or vibrati←↔ ng, a throttle valve is®✘ required to suppresγ₩λ s the damage of the pulsating pressure ∞ ¥to the meter.
