SEESAW TYPE OPERATION KNOB, AND SEESAW SWITCH USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a seesaw type operation knob capable of preventing breakage of a tact switch in spite of addition of external force while preventing generation of rubbing noises at the time of operation of the knob. SOLUTION: A projection 532 is arranged on an inner inclined face 531b of the top face 531a of a left push bar 53 of the seesaw type operation knob 5. The projection 532 is formed to be smaller than the inner inclined face 531b, and the top face 532a is formed to be round. An outer inclined face 531c of the top face 531a is formed to keep in contact with an upper face 112a of a movable terminal section 112 when the projection 532 makes the movable terminal section 112 of the left tact switch 11 hollow by adding the external force on the operation knob 5.
