Embodiment Construction
[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.
[0019] like figure 1 The button switch of a locking mechanism shown includes a push rod 2, a block 3, and a movable contact piece 5; the block 3 is rotatably fixed below the push rod 2, the push rod 2 can move up and down, and the bottom of the block 3 passes through The slider 4 is in contact with the moving contact piece 5. The moving contact piece 5 is an arc-shaped block bent upwards. Two contact pieces are respectively fixed below the two ends of the moving contact piece 5. The moving contact piece 5 can be rotated along both sides at the center position as the center of the circle. ; When the push rod 2 moves down, it can push the seat block 3 to rotate.
[0020] The push rod 2 is vertically facing the rotation center point of the seat block 3, and the position of the seat block 3 corresponding to the push rod 2 is an incli...

Abstract
The present invention provides a push button switch with a locking mechanism, which includes a push rod, a seat block, and a movable contact piece; the seat block is rotatably fixed under the push rod, the push rod can move up and down, and the bottom of the seat block is in contact with the movable contact piece through a slider , the moving contact piece is an arc-shaped block bent upwards, and two contact pieces are respectively fixed below the two ends of the moving contact piece, and the moving contact piece can rotate along both sides with the center position as the center of the circle; The block rotates. The invention adopts the swing angle of the seat block and the push rod to realize the locking function, which improves the reliability of the locking function and reduces the dependence of the switch on the precision requirements of the parts, so it has the advantages of high locking reliability and high life times, and the parts are The accuracy requirement is low.
Description
technical field [0001] The invention relates to a locking mechanism push button switch. Background technique [0002] like figure 2 The push button switch shown is a switch in which the internal contacts are switched by actuating force in line with the travel of the button. There are two types of locking mechanisms for common push button switches: cam type and hook spring type. These two kinds of locking mechanisms have low life times, and their locking reliability mainly depends on the high precision of the parts, the reliability is poor, the processing costs of the parts are high, and the structure of the locking mechanism is complicated. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a locking mechanism push button switch, which has the advantages of high locking reliability and high life times, and has low requirements on the precision of parts. [0004] The present invention is achieved through the ...
