A method of manufacturing a snap-acting plate comprises clamping marginal portions of the plate, applying pressure to one side of the plate to cause deformation, and then applying pressure alternately to either side of the plate to stabilize it. A plate 7 is held between a fixed holder 3 and a holder 5 movable by a fluidoperated piston 25 and pressure is applied hydraulically by a pump 65 and a two-way valve 53 to one or other side of the plate. The plate is deformed against an adjustable stop 31 or 33. The holders 3 and 5 are sealed by a ring 13 and located by pins 17, the plate being supported by ledges 19 in the holders. The plate 7 may be bimetallic, and for thermally responsive discs the temperature at which snap over occurs, which is correlated to the snap over pressure, is determined by measuring this pressure using gauges 48 and 50. Pneumatic pressure may be used for deformation, or as in Fig. 6 (not shown) mechanical apparatus. A plate 97 is held between holders 99 and 91 which are held together against the action of springs 105 by lever operated wedges 111. Pressure is exerted on the plate by stops 183 and 187 by motor driven screws 139 and 169, deformable rings 173 and 175 transmitting this pressure. To the top and bottom of the rings are mounted the relatively movable parts of a differential transformer 193, so that deformation of the ring produces an output giving a measure of the pressure exerted on the plate.
