A switch device includes: a printed circuit board provided with a connector; a rubber sheet; an operating knob; an operating mechanism; an operating mechanism plate; and a housing having a side surface provided with an insertion hole and a bottom surface provided with a discharge hole. The rubber sheet has a connector portion discharge path configured to guide the liquid entering the housing through the insertion hole to the discharge hole. The connector portion discharge path has one end connected to a part of the rubber sheet covering the connector, extends to be inclined from the one end toward the discharge hole provided on the bottom surface, and has the other end formed in a vicinity of the bottom surface and separated from the rubber sheet covering the connector. A gap exists between a lower end portion of the rubber sheet covering the connector and the other end.

A switch device includes: a printed circuit board; a rubber sheet configured to cover the printed circuit board; an operating knob; an operating mechanism; an operating mechanism plate; and a housing having a side surface provided with an insertion hole, and a bottom surface provided with a discharge hole for discharging liquid entering an inside of the housing; and a back cover that is fitted from a back side of the housing and sandwiches an entire periphery of the rubber sheet with a stepped portion formed inside the housing. The printed circuit board is stored in a space between the back cover and the rubber sheet. The discharge hole is located in a lower portion of a space between an inner surface of the housing and the rubber sheet. A bottom portion exists between the discharge hole and the rubber sheet.

An electric pushbutton switch includes a guide housing, a switching element having a haptic element that produces a pressure point and a return spring that generates a restoring force, an actuator for actuating the switching element, and a resilient tolerance compensation element arranged between the guide housing and the actuator. The switching element being stationary relative to the guide housing and the actuator being movable relative to the guide housing. The actuator actuates the switching element against the restoring force when the actuator is moved relative to the guide housing in an actuating direction of the actuator towards the switching element. The resilient tolerance compensation element is arranged between the guide housing and the actuator. The resilient compensation element has a spring force directed in the actuating direction of the actuator towards the switching element and opposite the restoring force of the return spring of the switching element.

A switch device includes a plurality of lead frames that is conductive and configured to electrically connectable to an external device, a contact-separation mechanism configured to allow the plurality of lead frames to be electrically connected to and separated from each other, and an electric element configured to connect the plurality of lead frames to each other.
