Embodiment Construction

[0044] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0045] 〔basic structure〕

[0046] Such as Figure 1 ~ Figure 3 As shown, the push switch is configured to include an operating member 10, an operating member 20, a housing 30, a first spring 51 as a first urging mechanism, a second spring 52 as a second urging mechanism, a switch unit 40 and Holding mechanism A that functions as a locking mechanism.

[0047] The push switch is configured such that, for example, in a gas cooking appliance, by repeatedly pushing the key 11 in, ignition of gas, maintenance of combustion and fire extinguishing can be realized, and the operation status can be confirmed according to the position of the key 11 . In addition, when used for gas cooking equipment, it is used in such a manner that the supply and discharge of gas are controlled by the control device based on the conduction state between the movable contact 43 and the fixed contact 42 cons...

Abstract

The present invention provides a push switch. The operating member (10) and the actuating member (20) of the push switch can be supported by a housing (30) movably along an operating line and the push switch is provided with a switch section (40) for obtaining an electrical conduction state corresponding to the position of the operating member (20). Further, the push switch includes a holding mechanism (A) for holding the operating member (10) at a predetermined operation holding position and holding the operating member (20) at a predetermined operation holding position. The holding mechanism (A) has a core-shaped cam groove (55) and a hook (56) having an engaging end portion (56b) that engages with the cam groove (55), and holds the actuating member (20) at the operation holding position based on the position of the engaging end portion (56b).

Description

technical field [0001] The present invention relates to a push-button switch which maintains an operating part in a plurality of operating positions by human push-in operation. Background technique [0002] As a push switch configured as described above, Japanese Patent Application Laid-Open No. 2007-323829 discloses a technology in which a key top and a slider are freely movable up and down with respect to a box-shaped case. In this technology, a spring biasing the key head in the protruding direction, a spring biasing the slider in the direction of contacting the key head, and a switch contact operated in accordance with the movement of the slider are provided. Equipped with a locking mechanism to lock the slider. [0003] In addition, in Japanese Patent Laid-Open No. 2007-323829, the locking mechanism is constituted by a heart-shaped cam groove formed on the slider, and a hook pin having one end engaged with the cam groove. Thus, when the key top is pressed, the slider ...
