  • Patent number: 9129762
    Abstract: There is provided a push switch including an insulating case, a conductive member, a movable electrode and an operating member. The insulating case has a wall portion defining a recess. The conductive member has a first portion embedded into the wall portion and a second portion disposed in the recess as a fixed electrode. The movable electrode is disposed in the recess and is displaced between a first position and a second position. The operating member is moved to displace the movable electrode from the second position to the first position. An anchor member protrudes from the conductive member in a direction not parallel to the direction in which the operating member is moved, and embedded into the wall portion.
    Type: Grant

  • Patent number: 8115130
    Abstract: A switch-type electronic device adapted to be mounted on a circuit board is disclosed. A housing is made of an insulative material. The housing includes a first face adapted to oppose the circuit board and a second face intersecting with the first face and formed with a projection. A cover is made of a conductive material. The cover includes a first part covering a side of the housing opposite to the first face, at least one second part extending from the first part and opposing the second face, and a third part extending from each of the at least one second part and engaging with the projection. An operating member includes a first part disposed outside the housing and adapted to be operated by a user, and a second part disposed in the housing and configured to switch the electronic device between a first state and a second state when the first part is operated by the user.
