Definitions

  • the present invention relates to a small pushbutton switch to be operated by being pushed by a control key.
  • a well-known type of pushbutton switch is generally composed of a housing with a fixed contact at the inner bottom facing an opening thereof, a movable contactor, also called a metal contact, which is housed inside the housing and is able to move into contact with and apart from the fixed contact, a vertically movable stem mounted on the movable contactor, and a metal housing mounted on the housing so that it covers the opening and thereby regulates the upward movement of the stem.
  • a pushbutton switch including a housing with a fixed contact at the inner bottom facing an opening thereof, a movable contactor housed inside the housing and being able to move into contact with and apart from the fixed contact, and a vertically movable stem mounted on the movable contactor and having an operating projection projecting upward from the housing through the opening, the movable contactor being brought into contact with the fixed contact by pushing the operating projection of the stem through a control key with a predetermined stroke, wherein the housing is provided with a stopper section projecting from the rim of the opening toward the control key, and wherein the stopper section is brought into contact with the control key when the stem is pushed a required amount by the control key.
  • the stopper section which is formed integrally with the housing, can be located with a high positioning accuracy with respect to the fixed contact and the movable contactor in the housing, the lowermost point of the control key can be accurately set by the stopper section to such a height that the stem can be properly pushed.
  • a metal frame for partly covering the opening and restricting the upward movement of the stem is mounted on the housing, the outer portion of the stopper section is projected as a hook portion from the outer surface of the side wall of the housing, and a mounting hole of the metal frame is retained by the outer portion. Therefore, the stopper section can be provided with a function of defining the lowermost point of the control key and a function of serving as a hook portion for mounting the metal frame.
  • Fig. 1 is a plan view of a pushbutton switch according to an embodiment of the present invention.
  • Fig. 2 is a side view of the pushbutton switch shown in Fig. 1.
  • Fig. 3 is a cross-sectional view taken along A-A of Fig. 1.
  • Fig. 4 is a cross-sectional view taken along B-B of Fig. 1, and;
  • Fig. 5 is an exploded perspective view of a pushbutton switch according to another embodiment of the present invention.
  • Fig. 1 is a plan view of a pushbutton switch according to an embodiment of the present invention
  • Fig. 2 is a side view of the pushbutton switch shown in Fig. 1
  • Fig. 3 is a cross-sectional view taken along line A-A of Fig. 1
  • Fig. 4 is a cross-sectional view taken along line B-B of Fig. 1.
  • the pushbutton switch shown in these figures mainly includes a housing 1 molded in one piece and having a fixed contact 2 located at the inner bottom facing an opening la and terminals 3 led out from the sides of the housing 1, a movable contactor 4, also called a metal contact, which is housed inside the housing 1 and is able to move into contact with and apart from the fixed contact 2, and a vertically movable stem 5 which is mounted on the movable contactor 4 and is provided with an operating projection 5a projecting upward from the housing 1 through the opening 1a.
  • the pushbutton switch is placed opposed to a control key 7 in the pressing direction.
  • the height of the stopper sections 1c is properly set so that the movable contactor 4 is in secure contact with the fixed contact 2 without causing any excessive stress concentration onto the stem 5 and the movable contactor 4 when the top face of the stem 5 is pusned down to the lowermost point.
  • the stem 5 cannot be further pushed in after the control key 7 makes contact with the stopper sections 1c of the housing 1, that is, the lowermost point of the control key 7 to be pressed is regulated by the stopper sections 1c.
  • the height of the top faces of the stopper sections 1c, which are formed integrally with the housing 1, with respect to the fixed contact 2 and the movable contactor 4 in the housing 1 can be determined with a high positioning accuracy, the lowermost point of the control key 7 is accurately set by the stopper sections 1c to such a height that the stem 5 can be properly pushed, as mentioned above.
  • Fig. 5 is an exploded perspective view of a pushbutton switch according to another embodiment of the present invention. Components corresponding to those in Figs. 1 to 4 are denoted by the same numerals.
  • a metal frame 6 that partly covers the opening la to restrict the upward movement of the stem 5 is mounted on the housing 1.
  • the fall-preventive sections 1b in the aforesaid embodiment are omitted, and the stopper sections 1c are slightly different in shape from those of the aforesaid embodiment. That is, in this embodiment, the outer portions of the stopper sections 1c are formed into hook portions 10c that project from the outer surfaces of side walls of the housing 1 to form overhangs, and a mounting hole 6a of the metal frame 6 is retained by the hook portions 10c. Accordingly, even if a bending length L of the metal frame 6 is set considerably shorter than the normal length, the metal frame 6 can be securely mounted on the housing 1.
