KEY SWITCH
Document Type and Number:
Japanese Patent JP2017204419
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a key switch which can prevent an erroneous operation.SOLUTION: A key switch according to the present invention comprises: a lock pin 8p; a solenoid 8 which causes the lock pin 8p to move forward/backward; a lock plate 7 which restricts the forward movement of the lock pin 8p before reaching a drive position p2 from a non-drive position p0, and which is locked to the lock pin 8p at the drive position p2 so as to be restricted from rotating; and a control part which turns on/off the solenoid 8. A conduction start position p1 is provided so as to start bringing a target device R into conduction when rotating a key 1 to the drive position p2. The lock plate 7 has: an opening 7k which permits the forward and backward movements of the lock pin 8p when the key 1 is rotated toward the drive position p2; and a locking part 7d, formed on an inner wall of the opening 7k, which restricts the rotation toward the non-drive position p0 by coming into contact with the lock pin 8p when the key 1 is rotated from the non-drive position p0 to the conduction start position p1.SELECTED DRAWING: Figure 3
