PURPOSE:To enable the time required for operation to be reduced by configurating a device in such a manner that a command switch for raising and dropping the temperature within the preset limit is made up of a pressure adjustable one so as to control the adjustment of the adding and subtracting of data through an operating device in response to the pressure applied to the switch. CONSTITUTION:Both an UP switch 1 and a DOWN switch 2 are made up of common terminals 1C and 2C, electrodes 1A and 1B, and 2A and 2B, each of which has a different contact point in height, and of movable electrodes 1E and 2E which are spring loaded by springs 1D and 2D, and are connected to ports PA through PC of a microcomputer 3. The microcomputer 3 allows the rate of temperature rising and dropping to the present temperature to be determined by detecting an operating stroke of each of switches 1 and 2. If an operator desires to raise the temperature drastically, the UP switch 1 can be depressed more strongly than usual so as to connect the terminal 1C with the terminal 1B allowing the preset temperature to be quickly attained while the microcomputer 3 permits the rate of temperature rising to be increased by the specified increment. |
