  • Main button: The button that causes the On/Off operation to be performed by exerting force on it.
  • It is the primary tool for completely sealing the button so that it remains protected from moisture and other objects, such as dirt or dust, that, upon entering, cause the switch to be damaged.
  • A semi-elliptical spring is slightly elliptical. Its end is connected to a contact. When the operation button is pressed, the contact is transferred to a fixed one. Then, it applies much contact pressure to ensure a secure connection between the two. Contact welding is prevented when it is turned off due to an increase in the release of contact force.
  • Case inside and lid: the parts that go into the switch mechanism. In the case, which also serves as a seal, are terminals, contacts, and semi-elliptical springs.
  • Cover A resin portion covering the interior sealed casing. The sealing rubber is also fixed in place using it. In addition, it makes it simple to attach the switch within a square panel hole.
  • Contacts and terminals: The fixed contact is created by affixing a contact to the end of one of the terminals.
