Abstract

This invention provides a composite operation type switch device, in which no flux will intrude inside the switch device even when the switch device is mounted on the circuit board by the reflow soldering method. The structure of the invented composite operation type switch device includes a containing portion having a bottom face and side faces sealed and formed on a base member attached with a cover member and thus the switch structure element is disposed in the containing portion. Through the use of the structure, during reflow soldering process of the composite operation type switch device, even if the reflow soldering material has contact with lower side of the bottom face of the base member, the soldering material will not intrude into the containing portion from the bottom face because the bottom face of the base member is sealed. Therefore, the invented composite operation type switch device using the reflow soldering method to be mounted on the circuit board can be obtained.
