LIQUID LEVEL SENSOR

摘要

A liquid level sensor that can be easily assembled by simply placing members one upon another without the need of soldering. A thermistor element (7) is sandwiched by an electrode (2a) of an element holder (2) and an electrode (3a) of a terminal (3). A coil spring (4) is inserted along the terminal (3) so that the electrode (3a) presses into the thermistor element (7). An insulator (5) to which a terminal (6) is fitted by caulking is placed at a fitting portion (2c) of the element holder (2) and these members are inserted in a metal case (1) so as to close the opening of the metal case (1). A fitting portion (2c) of the element holder (2), and a fitting portion (1a) of the case (1) are fitted in a cut-away portion (5c) of the insulator (5).
