    • PURPOSE:To provide a control switch hard to cause unevenness of angle properties even when an external leading out line is sealed by forming a hollow part separated from a part which seals a connecting part of an external leading out line by a rib in a recessed part of a cover and forming a small hole which is communicated with a storage chamber in the hollow part. CONSTITUTION:A hollow part 21 separated from a part which seals a connecting part of an external leading out line bay a rib 23 is formed in a recessed part 18 of a cover 2 and a small holes 22 which is communicated with a storage chamber 5 is formed in the hollow part. The small hole 22 has an inner diameter becoming smaller as it goes farther to back side and a shape extruding to the back side, so that the hole is sealed easily by thermal deposition after sealing the recessed part 18. In the case that the cover 2 is formed in this way, the storage part 5 does not become in sealed state during the sealing process and thus expansion of the cover 2 owing to the increase of the inner pressure of the storage part 5 is prevented at the time of drying a sealing agent at high temperature during the sealing process and consequently, unevenness of angle properties is hardly caused.
