不可能となる欠点がある。 Conventionally, this type of enclosed limit switch has a built-in switch that is attached to the housing with a screw, but this requires a large space for tightening the screw, and it is especially difficult to provide an opening at the bottom of the housing for inserting the switch. However, it is difficult to downsize the products. Further, as shown in FIG. 1, both ends of pins 8, 8, which pass through the mounting holes 9, 9 of the switch 2, are press-fitted into the grooves 7, 7 provided on the inner wall of the housing 1, and the pins are temporarily attached to the housing 1. There are some that are fixed and then permanently fixed with a filler, etc. Similar to the former case, if the housing 1 has an opening at the bottom, an external plunger 4 is provided.
The force is applied directly to the built-in switch 2, and therefore the pins 8, 8 are always subjected to a force in the direction of removing the pins, which may prevent reliable fixation. In some cases, a hole 10 is provided in which the pin 8 is inserted, and a filler 19 is filled in the housing 1 to ensure the sealing performance of this hole, but this has the disadvantage that it is impossible to connect the terminals of the switch 2. be.
この考案はこのような従来の欠点を解消しよう
とするもので、以下図によつてこの考案の一実施
例について説明する。 This invention is intended to eliminate such conventional drawbacks, and one embodiment of this invention will be described below with reference to the drawings.

けられる。 That is, in FIGS. 3 and 4, a snap actuating switch 2 is housed within the housing 1. As shown in FIGS. A round hole 3 is provided at one end of the housing 1, and an external plunger 4 is slidably inserted into this hole. Furthermore, the other end of the housing 1 is provided with an opening 5 through which the switch 2 is accommodated within the housing 1. In the inner walls of the housing 1 facing each other, stepped protruding wall parts 6, 6 are provided near one end thereof, and notches 7, 7 are provided in these protruding wall parts from the other end side. It is being The mounting pins 8, 8 of the switch 2 are inserted into the mounting holes 9, 9, and both ends of the mounting pins 8, 8 are attached to the switch 2.
protrudes from both sides by a predetermined distance. Both ends of this pin are engaged with the notches 7, 7,
The pin is held in its engaged state by frictional force with the protruding walls 6,6. The pins 8, 8 are fixed to the protruding walls 6, 6 by caulking a part of the protruding wall 6 on both sides of the notches 7, 7 so as to narrow the dimensions of the notches. The switch 2 is thereby attached to the housing 1.

て現場での結線が容易になる利点がある。 As described above, this device provides stepped protruding walls 6, 6 near one end on the opposing inner walls of the housing 1, and furthermore, these protruding walls have a cutout from the other end. 7 is provided, and the mounting pins 8, 8 of the switch 2 are engaged with the notches while passing through the mounting holes 9, 9 of the switch 2, and the protruding wall portions are formed on both sides of the notches 7, 7. Since the switch 2 is fixed to the housing 1 by caulking a part of the parts 6 and 6, it is possible to securely fix it in a small space, and there is no need to fill it with filler as in the conventional case. This has the advantage of making on-site wiring easier.
