PURPOSE:To increase efficiency of operation process and reduce parts in stock, by providing a delay switching circuit part and an electric power supply circuit part on the respective exclusive substrates. CONSTITUTION:A delay switching circuit part A is formed on the first exclusive substrate 18, and an electric power supply circuit part B is formed on the second exclusive substrate 23. These first and second exclusive substrates 18, 23 are installed in one body to the parent substrate 13 together with the output relay 25 and the terminal assembly 27, and are stored in the case 10. The case 10 is constituted so that its opening part is closed by the terminal assembly 27, the shaft 20a of a hybrid small variable resistor mounted to the first exclusive substrate 18 corresponds to the inserting hole 11 of the case 10, and also the display LED22 corresponds to the display hole 12. |
