PURPOSE: To compose a small size switch without generating an impact noise on switching, and is free from the influence on the contacts of a lubricant in the driving part and the like, in a switch to open and close plural contacts at specific timings.
CONSTITUTION: By the motive power of a motor M, an output shaft 26 is driven through a reduction mechanism sealed in a gear box 20. To the output shaft 26, rotary cams 31, 32, 33, and 34 are fixed, and the switch mechanisms are driven by the rotary cams so as to open and close the contacts. The motor M is housed in a space at the lower side of the gear case 20, and the whole body is composed in a small size. And since the reduction mechanism is sealed in the gear case 20, the lubricant of the gear is never scattered to the contacts.
