The moving contact j of a snap-action switch, Figs. 1 and 3, is held against a pair of fixed contacts c, f by dead-centre springs t and the member h carrying the contact j bears against a hook o on a cam n so that movement of the cam in an anticlockwise direction by dolly r first causes the member h to move downwards and clean the contacts and then causes the contact j to snap over and bridge further fixed contacts b, e. Return movement of the dolly causes the contact j to move upwards against the contacts b, e and then, as the striker p abuts the member h, to snap back to its original position. During movement of the member h its upper part slides on the cam n between o and p. To ensure equal contact pressure, fulcrum pieces k are provided between the member h and the moving contact j and in the two-way switch shown the contacts c, b are formed from a single strip. Fig. 4 shows a switch having a pair of moving contacts j and a double cam n actuated by a knob x. A switch similar to that shown in Fig. 1 but having the cam spring-returned and operated by a plunger is also described, Fig. 6 (not shown).

[Also in Divisions G1 and H2] In a thermostatic system for controlling the operation of a valve 2, in which the pressure exerted by a vapour filled chamber 4 on a bellows is opposed by a spring 6, a setting knob 8 adjusts the force of a spring 6 non - linearly, to compensate for the non- linear increase in pressure in the bellows with rising temperature. The non- linear transmission ratio between the force of the spring and the setting knob 8 is obtained by the spring having a pitch which varies along its length. A valve member 1 on the rod 3 controls the valve 2 and a capillary tube 5 is connected to a temperature sensitive capsule (not shown) containing vapour. An indicator scale may be associated with the top of the knob 8. The desired non-linearity in the spring characteristic may also be obtained by using a conical spring or a stack of graduated disc springs. It is also proposed to use a linear characteristic spring which is compressed by a suitably shaped cam device actuated by the control knob.
