An oscillator capable of reducing a noise component when partly formed by using the CMOS process or the MOS process. The temperature sensor includes a circuit for detecting a first temperature threshold having a first detection threshold, and for detecting a second temperature threshold having a second detection threshold. A part of the connected portion is located within an imaginary region formed by imaginarily extending the line portion toward the land portion. The activation rail is pivoted when the door or window is being closed and causes the sealing element to engage the floor or window frame.
