Abstract

PURPOSE:To simplify the construction for small sized device and to decrease the cost, by the on/off control of output signal at preset values of a plurality, through the use of microprocessor executing the program in advance. CONSTITUTION:When preset value is stored in a random access memory RAM, by respectively depressing the 1st-3rd set button switches F, G, H among push button switches MS, the microprocessor MPU checks the content of memory RAM with counting operation, and the on-off signal according to the preset value is delivered to the switching element SW to control the external device and to display it on display devices 4-6 of the output display device DP3. Thus, with the power supply back-up of the memory RAM, when the count value and preset value are stored, it can be used the same or more as the digital switch system.
