Switch device and vehicle door outer handle system
A switch device includes: a switch housing case; a holder fixedly placed inside the case; a switch fixedly housed inside the holder; and multiple switch buttons each capable of making pressing force act on the switch. An intermediate cap integrally including a lid portion covering the switch and a tubular portion continuing to a peripheral edge portion of the lid portion is attached to the holder. A first deformation portion on the tubular portion deforms the tubular portion by pressing on the lid portion from a first switch button. A second deformation portion on the lid portion deforms a center portion of the lid portion by pressing on the center portion of the lid portion from a second switch button. Two types of switch buttons without making changes to the parts exclusive of the switch buttons becomes possible.
1. A switch device, comprising:
a switch housing case having an opening portion;
a holder, including a tubular holder main portion, fixedly placed inside the switch housing case in a position corresponding to the opening portion, at least one end, on the opening portion side, of the holder main portion being open;
a switch, including a portion to be pressed, housed in and fixed inside the holder main portion of the holder for changing a switching mode in response to a pressing force on the portion to be pressed;
at least one switch button configured to: include a press manipulation portion placed inside the opening portion, make the pressing force act on the switch in accordance with a manipulation of the press manipulation portion, and cover one end portion of the holder main portion,
wherein the holder is fixed to the inside of the switch housing case with the one end portion of the holder main portion opposed to an inner surface of a peripheral edge portion of the opening portion; and
an intermediate cap made of elastic material is attached to the holder to close one end of the holder main portion and integrally includes a lid portion and a tubular portion, the lid portion being configured to cause the pressing force to act on the portion to be pressed and cover the switch, the tubular portion continuing to a peripheral edge portion of the lid portion,
wherein the tubular portion includes a first deformation portion configured to deform the tubular portion to make an entirety of the lid portion press the switch in response to detecting at least a portion of the pressing force on the lid portion, and
the lid portion includes a second deformation portion configured to deform a center portion of the lid portion to make the center portion of the lid portion press the switch in response to detecting at least a portion of the pressing force on the center portion of the lid portion, and
wherein an end portion of the intermediate cap opposite from the lid portion is inserted into and joined to the one end portion of the holder main portion included in the holder by engaging recesses and protrusions of the end portions with each other.
2. The switch device according to claim 1 , wherein the intermediate cap and the holder are made of materials in combination which enable the intermediate cap and the holder to attach to each other due to hydrogen bond.
3. A vehicle door outer handle system in which at least one of locking and unlocking of a door is carried out by use of the switch device according to claim 2 ,
wherein the switch device is constructed by using any one of a manipulation handle and a base member as the switch housing case, the manipulation handle including a grip portion which is placed on an outside of an outer panel constituting part of the door and is formed long, the base member being attached to the outer panel corresponding to an end portion of the manipulation handle.
4. A vehicle door outer handle system in which at least one of locking and unlocking of a door is carried out by use of the switch device according to claim 1 ,
wherein the switch device is constructed by using any one of a manipulation handle and a base member as the switch housing case, the manipulation handle including a grip portion which is placed on an outside of an outer panel constituting part of the door and is formed long, the base member being attached to the outer panel corresponding to an end portion of the manipulation handle.
