U having a pair of contact portions that are inserted into the lever through the lever and project slightly from both surfaces of the thin portion.
A hugging type in which a V-shaped movable contact piece, a first fixed contact piece and a second fixed contact piece attached to the base body with the movable contact piece sandwiched therebetween, and a first fixed contact piece integrally projectingly provided. It is achieved by respectively including the holding connector and the locking portion provided in the space of the base for locking the holding connector.

[Operation] By rotating the operation lever rotatably provided on the base body with the hinge boss as a fulcrum by the hinge action of the hinge boss by the hinge piece, the first and second fixed contact pieces are provided with the operation lever of the operation lever. Conductive with a movable contact piece inserted in the opposing groove,
It can also be made non-conductive.

The vertical movement and the horizontal movement of the operating lever are blocked by the hinge pieces with respect to the hinge boss.

Further, by integrating the holding connector and the first fixed contact piece, the assemblability of the entire switch unit is improved, including the attachability of the first fixed contact piece and the sandwiching connection tool.

Furthermore, connect the other bulb base that faces the bulb base of the straight tube lamp inserted and connected to the holding connection tool to one pole of the power supply through the holding connection tool or other connection tool or bus bar as described above. By connecting the second fixed contact piece to the other pole of the power source and rotating the operation lever, the straight tube lamp or the like can be turned on / off via the conductor through the first fixed contact piece.
