Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0038] figure 1 is the external view of the lever switch of this embodiment, figure 2 is a sectional view of the lever switch. figure 1 and 2 The shown lever switch 1 includes various components such as a base 2 , a fixed contact 3 , an operating lever 4 , a housing 5 , a coil spring 6 , a rotor 7 , and a movable contact 8 .

[0039] The switch 1 includes a switch mechanism that makes the operating lever 4 rotate on the base 2 to switch the contact between the fixed contact 3 and the movable contact 8; Clearance, waterproof and dustproof mechanism to prevent foreign matter such as water or dust from entering the switch mechanism. The detailed structure of the switch mechanism part and the waterproof and dustproof mechanism part and the assembly sequence of each part are introduced below.

[0040] First, install the fixed contacts on the base (...

Abstract

It is an object of the present invention to provide a lever switch capable of reliably preventing intrusion of water or the like into a casing and maintaining smooth operation of a switch mechanism for a long period of time. A lever switch provided with a switch mechanism whereby an operation lever rotates from a neutral position on a base against a spring force of a coil spring to change the position of the switch, a gap between the operation lever and base is filled with a casing, the switch mechanism is accommodated in the casing and a waterproof / dustproof mechanism is provided to seal a sliding surface between the operation lever and casing and a contact surface between the base and casing with an upper lip packing and lower lip packing respectively.

Description

technical field [0001] The present invention relates to a switch for detecting the opening and closing state of, for example, a power window of a vehicle, and more particularly to a lever switch requiring waterproofness and dustproofness in its use environment. Background technique [0002] Conventionally, as a switch having such characteristics, a waterproof lever switch filed and disclosed by the present applicant is known (for example, refer to Patent Document 1). [0003] The switch has such a structure that a movable contact spring piece is provided on the underside of a circular plate protruding from the periphery with a lever, and a fixed contact is arranged on the underside of the movable contact spring piece. Once an external force acts on the lever, the protrusion under the circular plate that rotates against the elastic force pushes the movable contact spring, and the movable contact spring bends and contacts the fixed contact, thereby closing the switch. In addi...
