<P>PROBLEM TO BE SOLVED: To provide a push button switch in which floating of an adhesive tape is suppressed when performing reflow soldering. <P>SOLUTION: A push button switch 100 includes an adhesive tape 20 which seals an opening 15 of a housing 10. On the bottom face 17 in the housing 10, a fixed contact 12 is provided, and a movable contact 13 is provided in the housing 10. The adhesive tape 20 consists of a support base material 21 and an adhesive layer 22. The adhesive layer 22 of the adhesive tape 20 is in contact with a portion (18) of the housing 10 and a portion of the movable contact 13. The support base material 21 of the adhesive tape 20 has a thickness of 25 μm or more to 100 μm or less, the difference of vertical and horizontal dimensional change of the support base material 21 after heating is in a range of ±0.01% or more and ±6% or less, and the tensile strength of the support base material 21 is 0.7 N/mm or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
