摘要： A method of testing a secondary battery includes first to fourth steps. At the first step, the secondary battery after manufacture is charged to a first voltage. At the second step, a second voltage lower than the first voltage is set as a target voltage and discharge or charge is performed in a constant-current constant-voltage mode before the secondary battery is left standing. At the third step, the open circuit voltage of the secondary battery is measured before and after the secondary battery is left standing. At the fourth step, it is determined whether the secondary battery is a conforming item or not based on the difference in the open circuit voltage before and after the secondary battery is left standing.

摘要： A built-in indicator switch unit include an indicator and a switch within a casing so that the switch is operated by a pushing operation applied to a light-transmissible operation cover provided in the front side of the indicator. The switch is actuated by an operation mechanism which inverts the pushing force exerted on the operation cover to an opposite direction in response to the pushing operation applied to the operation cover. The indicator and switch are attached to a printed circuit board arranged in the casing, substantially in parallel to the front surface of the casing and projecting out at one end from the casing.
