Abstract
A switch device includes a lock component and a crossbar. The crossbar is configured to open or close electric contacts. The crossbar includes a lock receiving section for receiving the lock component after the switch device is turned to an ON position for a period of time. The lock component is disengaged from the lock receiving section after the period of time to allow the crossbar jump upwards to close the electric contacts quickly.
Claims18
A switch device for opening and closing electric contacts, comprising:
- a lock component comprising a spring portion and a lever portion;
- and
- a crossbar defining a lock receiving section for engaging with the lever portion,
- wherein the lever portion is pushed by the spring portion to be engaged with the lock receiving section and hold the crossbar in a lock position when the switch device is in an OFF operational mode,
- wherein when the switch device is switched to an ON operational mode, the crossbar is initially in the lock position until the lever portion is moved to disengage from the lock receiving section and release the crossbar from the lock position to enable movement of the crossbar;
- wherein the lever portion is pushed away from the lock receiving section by a spring reaching and contacting an unlock point of the lever portion.

A switch device for opening and closing electric contacts, comprising:
- a lock component comprising a spring portion and a lever portion;
- a crossbar defining a lock receiving section for receiving the lever portion of the lock component,
- a lever connected between the crossbar and an operating element, and
- a spring connected to the lever,
- wherein when the switch device is in an OFF operational mode via the operating element being in a first operating element position, the spring is configured to move the lever which moves the crossbar into a lock position in which the lock receiving section is able to receive the lever portion of the lock component, and the spring portion of the lock component is configured to force the lever portion of the lock component into the lock receiving section to hold the crossbar in the lock position and prevent movement of the crossbar,
- wherein when the switch device is in an ON operational mode via movement of the operating element from the first operating element position to a second operating element position, the lever is moved via the movement of the operating element thereby causing the spring to contact an unlock point on the lever portion of the lock component, the spring is configured to push the lever portion of the lock component out of the lock receiving section and compress the spring portion of the lock component, and the crossbar is released from the locked position to enable movement of the crossbar.
