`
`l.
`
`A push switch mounted on an printed circuit board,
`
`comprising:
`
`an operation portion which is pushed and operated from
`
`adirectionparalleltoaasurfaceofthenmuntedprintedcircuit
`
`board;
`
`aipluralityiof contacts which are electrically conducted
`
`by the push operation of the operation portion;
`
`a case which is formed from an insulation body and has
`
`10
`
`a lower surface facing the printed circuit board;
`
`a plurality of terminals which are led out from the case
`
`to outside; and
`
`a embedded portion which is physically and electrically
`
`connected to any one of the plurality of terminals and embedded
`
`15
`
`and fixed inside the case,
`
`wherein an exposed portion is formed in a part of the
`
`embedded portion so as to be exposed to the outside from the
`
`lower surface of the case.
`
`.
`
`2.
`
`The push switch of Claim 1,
`
`20
`
`25
`
`wherein the exposed portion is formed in the central
`
`portion of the embedded portion.
`
`3. The push switch of Claim 1,
`
`wherein the exposed portion is an exposed portion to be
`
`soldered.
`
`4.
`
`The push switch of Claim 1,
`
`19
`
`
`
`wherein the exposed portion is recessed more than the
`
`lower surface of the case.
`
`5. The push switch of Claim 1,
`
`wherein the exposed portion.has a protrusion protruding
`
`from the lower surface of the case.
`
`6. The push switch of Claim 1,
`
`wherein
`
`the
`
`terminal which
`
`is
`
`physically
`
`and
`
`electrically connected to the embedded portioin is an earth
`
`terminal which is electrically independent from.the contacts.
`
`10
`
`7. The push switch of Claim 1 or 6,
`
`wherein the embedded portion having the exposed.portion
`
`formed therein is physically and electrically connected to a
`
`terminal provided at the closest position to the side where
`
`the operation portion receives the push operation among the
`
`15
`
`plurality of terminals.
