Abstract
In a switch with pre-alarm means having level adjusting apparatus (105a) of the pre-alarming and an indicator (103) for showing that value of current flowing on a load corresponds to the pre-alarm level, the level adjusting apparatus (105a) is adjusted with monitoring the indicator (103). When the indicator (103) is lighted, the value shown by level indicator (105b) of the level adjusting apparatus (105a) corresponds to actual value of the current flowing on the load at that time.
