Embodiment Construction

[0021] An embodiment of the present invention will be described below with reference to FIGS. 1 to 8 . This embodiment is an example in which the present invention is applied to a window lock switch of an automobile. First, in FIGS. 1 to 4 , a stepped receiving portion 12 with upper and lower openings is provided in the switch main body 11 , and a rectangular operation button guide 13 is provided around the receiving portion 12 . A cam groove 14 as shown in FIGS. 4 and 8 is formed in the inner peripheral portion of the large-diameter portion 12 a on the lower side of the housing portion 12 .

[0022] In the cam groove 14 , a lock release groove 15 that is deeper upward and a lock groove 16 that is shallower than that are alternately formed at intervals of 30 degrees. Therefore, six unlocking grooves 15 and six locking grooves 16 are formed at equal intervals over the entire circumference. Among them, two vertical surfaces 15a are formed in the lock release groove 15, and an ...

Abstract

To prevent a twist of a switch element in constitution in which an operation knob is alternately held in a locking position and an unlocking position by pressing the operation knob. When the operation knob 18 is pressed, a rotor 32 is rotated by a first cam mechanism 37, the switch element 40 is turned on by a pusher 25 moving together with the operation knob 18 when pushing is released, the rotor 32 is held in the locking position by a second cam mechanism 39, and the operation knob 18 and the pusher 25 are held in the locking position. When the operation knob 18 is pressed again, the rotor 32 is rotated and unlocked, and when pressing is released, the rotor 32 is returned to the unlocking position, the operation knob 18 and the pusher 25 are returned to the unlocking position, and the switch element 40 is turned off.

Description

technical field [0001] The present invention relates to a switch device having a structure in which an operation button is alternately held at a locked position and an unlocked position when the operation button is pressed. Background technique [0002] As such a switch device, for example, a device having a structure shown in FIGS. 9 and 10 is known (refer to Patent Document 1). The structure of the device is as follows. That is, in the stepped receiving portion (holding hole) 2 provided on the switch main body 1, an operation shaft body 3 capable of reciprocating movement in the axial direction is provided, and an operation button (operation button) is provided on the upper end of the operation shaft body 3 . disc) 4, and at the same time, a rotatable rotating body (rotating body) 5 is provided at the lower end. Between the operation shaft body 3 and the rotation body 5, there is provided a first cam mechanism 6 that rotates the rotation body 5 based on the pressing oper...
