<P>PROBLEM TO BE SOLVED: To easily attach and detach a push button switch from a case body and to easily repair and inspect the same. <P>SOLUTION: An attaching hole 54 and an opening 22 is formed in the case body 23. The switch body is accommodated in an attaching cylinder 62. An operating cap 60 is fitted on one end part of the attaching cylinder 62 so as to cover the switch body. The pushing button switch body 50 is inserted in the attaching hole 54. An attaching groove 64 is formed in the outer peripheral surface of the attaching cylinder 62 projecting to the inside of the case body 23. A fixing wedge 51 is inserted from the opening 22 and is inserted into the attaching groove 64. The inclined surfaces 53, 68 of the attaching groove 64 and the fixing wedge 51 contact with each other and bias the attaching cylinder 62 inward in the first direction A1. By the biasing, the end fringe part 60c of the operating cap 60 contacts the engaging step part 71 of the attaching hole 54 and deforms and brings the attaching hole 54 and the operating cap 60 into airtight close contact with each other. The push button switch body 50 can be easily attached to and detached from the case body 23 by the inserting and drawing of the fixing wedge 51. <P>COPYRIGHT: (C)2013,JPO&INPIT |
