SAFETY SWITCH WITH OVER-CURRENT PROTECTION

摘要

A safety switch with over-current protection has a switching button pivotally mounted on a housing. A linking member is pivotally mounted on one end of the switching button, and is linked to the switching button to oscillate according to on and off states of the switching button. One end of the linking member corresponds to a conductive plate in the housing for connecting to a power loop. The conductive plate has a first electrical connection part and a second electrical connection part formed on two ends thereof. When the power loop has an over-current condition, the conductive plate is deformed by the generated heat such that the normally-closed electrode contact above the conductive plate bounces off to disconnect from the power loop for over-current protection. As fewer parts are needed, fast assembly and economical cost can be achieved upon production.

主权项

1. A safety switch with over-current protection, comprising:
a housing being hollow, and having a chamber formed through a top of the housing and defined in the housing; a switching button pivotally mounted in the chamber of the housing and having:
an open bottom; anda pivot shaft formed on an inner wall of the switching button, wherein the inner wall protruding downwards and beyond the open bottom; a linking member taking the form of a slender plate, and pivotally mounted on the pivot shaft of the switching button for the linking member to oscillate together with the switching button; and a conductive plate being slender, mounted inside the housing, and having two electrode contacts formed on two ends of the conductive plate, wherein one of the electrode contacts is connected to a lower portion of the linking member.
