Abstract: 1,003,519. Thermal switches. CHRISTIAN BURKERT. Dec. 7, 1961 [Dec. 9, 1960], No. 43896/61. Heading H2B. A rod-and-tube thermostat device is latched magnetically against an actuating spring until expansion of the tube operates the switch. A strip 12, fastened in the rod 3, has two noses which pull an armature plate 9 away from a magnet 13 when the tube 1 expands and pulls the rod 3 downwards. Spring 18 then overcomes the magnetic force still existing and carries the magnet 13 and its base-plate 14 upwards to strike an insulating piece 25 and lift bridging contacts 23 off fixed contacts 22. Insulating piece 25 is pushed down manually to reset the switch upon cooling. Temperature setting is obtained via adjusting screw 17. Resetting of the insulating piece 25 is via a pushrod or through pivoted linkages or Bowden cables. The pot member 7 is adjustable axially via screw-threads or cams to vary the response temperature. Insulating piece 25 alternatively operates change-over contacts. Rod 3 may act on the armature plate through a lever arrangement and the magnet may alternatively be pulled away from its armature plate.
