FIELD: instrumentation engineering; pressure and temperature control and monitoring systems. ^ SUBSTANCE: proposed sensor-relay has bracket-accommodating case; knife-edge supports of this bracket mount double-arm vertical-bend drive lever. One arm of lever is pressed through rod and adjusting spring to sensing system by desired setting value. Other arm is free to act through insulating strap upon movable flexible plates carrying contacts held down in loose state to contacts of fixed contact plate. Sensor-relay also has axle-mounted intermediate lever. One arm of intermediate lever is coupled through adjusting spring of reset zone and screw-nut pair with case and its other arm abuts against vertical-bend knife-edge support through slide block. ^ EFFECT: ability of switching heavy currents at high sensitivity of sensor-relay. ^ 2 cl, 1 dwg
