Series DA-7035-N temperature switches |
 Series
DA-7035-N temperature switches include the same time-proven
switching mechanism used in our Series DA pressure switches.
Bourdon tube assures high sensitivity and long life. Fully
adjustable deadband makes units suitable for a wide range of
control applications. Visible, calibrated dial and external
adjustments make changing setpoints simple and fast. Dimensional Information
