いる。 FIGS. 1 and 2 show examples of conventional switches of this type. The switch 1 is provided with a pair of locking pieces 3 having free upper ends on both sides of an insulating case 2 in a cantilevered manner along the sides of the insulating case. Retreat gaps 4 for the locking pieces 3 are provided on the back surfaces of the locking pieces 3, respectively.
A flange portion 2A is provided on the upper outer periphery of the insulating case 2 except for the locations of the respective locking pieces 3. Each locking piece 3 has an extraction jig locking protrusion 3a and a switch locking protrusion 3b.
is provided protrudingly. Such a switch 1 is fitted into a hole 6 of a support 5 such as a printed circuit board, and at this time, the lower surface of the flange 2A is engaged with the upper surface of the support 5, and the upper surface of the switch locking protrusion 3b is engaged with the upper surface of the support 5. The switch 1 is engaged with the lower surface of the switch 1 to prevent the switch 1 from coming off. In this state, the extraction jig locking protrusion 3a is
It is provided so that a gap is created between it and the support body 5.

できる。 When such a switch 1 is to be pulled out from the support 5 for some reason, the holding protrusions 9A and 9B provided on the respective clamping pieces 8A and 8B of the pulling jig 7 as shown in FIG. Protrusion 3a
Each locking piece 3 is inserted into the gap between the
is pushed back to the retreating gap 4 side, thereby removing the switch locking protrusion 3b from the support 5, and while maintaining this state, pulling up the extraction jig 7, the presser protrusions 9A and 9B lock the extraction jig. The switch 1 can be pulled out from the support body 5 by being engaged with the protrusion 3a.

うにして設けられている。 A specific example of the invention will be explained in detail below with reference to the drawings. As shown in FIGS. 4 and 5, in the switch 1 of this embodiment, the extraction jig locking protrusions on the pair of locking pieces 3 on both sides of the insulating case 2 are omitted, and the locking protrusions are used to lock the switch. Only the protrusion 3b and the extraction jig holding protrusion 3c protrude from the upper surface of the support. Instead, extraction jig engagement recesses 10 are provided in the flange 2A of the insulating case 2 adjacent to both sides of the locking piece 3 so that the lower surface and the surface facing the locking piece 3 are open. There is.
