CONNECTOR CONNECTION DETECTING CIRCUIT

摘要

PURPOSE: To prevent electric power from being supplied when the connection of a connector itself is unstable. CONSTITUTION: A switch 2 is arranged so that it is pressed to be turned on when the connector part 4a of a module 4 is inserted into the connector part 1a of a system main body 1 to reach a specific position, namely, when the connector part 4a begins to come into contact with the connector part 1a. A switch 3 is so arranged as to turn on by being pressed when the connector part 4a completely engages the connector part 1a. The switches 2 and 3 both return to turned off state when the connector part 4a is disengaged from the connector part 1a.
