Part No.: 183-5035




Illustration 1g00879545

(1) Torque for the pressure switch ... 35 ± 3 N·m (26 ± 2 lb ft)

(2) Schematic symbol

Actuation pressure at -40°C to +121°C (-40°F to +250°F) ... 295 kPa (43 psi)

Deactuation pressure at -40°C to +121°C (-40°F to +250°F) ... 230 ± 20 kPa (33 ± 3 psi)

Contacts 1 and 2 are normally open below the deactuation pressure of the pressure switch.
