Switch device

A switch device comprising:

• a substrate having one surface and another surface;
• a switch disposed on the one surface of the substrate and configured to be pressed;
• a first housing;
• a second housing;
• and
• a pin member,
• wherein an internal space is formed by the first housing and the second housing, the substrate being disposed in the internal space,
• wherein the first housing has an opening through which at least a part of the pin member is inserted into the internal space,
• wherein the second housing includes a support portion that supports the another surface of the substrate, and
• wherein, when the pin member is inserted into the internal space through the opening, the pin member presses the support portion against the another surface of the substrate so as to cause the support portion to support the another surface of the substrate,
• wherein the first housing includes a support plate portion that extends toward the second housing,
• wherein the substrate has a through-hole, and
• wherein the support plate portion passes through the through-hole and is disposed through the substrate.
