Problems solved by technology

[0006] However, when adopting such a structure that does not generate an arc, components such as a control circuit board and a relay are required, which increases the cost of the refrigerator.
In addition, it has also been proposed to operate the contact part of a highly sealed switch by moving the plunger up and down (for example, refer to Patent Document 1). However, since the vertical stroke of the plunger must be increased, the overall size of the switch will be reduced. increased, and there was a problem that miniaturization was not possible

Embodiment Construction

[0030] An embodiment of the present invention will be described with reference to the following drawings.

[0031] The accompanying drawing shows a rotary switch used as a door switch for a refrigerator, figure 1 , figure 2 , image 3 The rotary switch 11 is formed by integrally assembling the housing 12, the cover 13, the rotary lever 14, the return spring 15 and the sealed switch 16.

[0032] The housing 12 has a concave hollow portion 12a into which the above-mentioned components 14, 15, 16 are assembled. After the components are assembled in the hollow portion 12a, a cover 13 is integrally installed to seal the opening of the hollow portion 12a. face forms a plane.

[0033] Figure 4 Represents the rotating lever 14, which is fan-shaped, and the lever pressing piece 14a is extended obliquely upward along an inclined surface of the fan-shaped, and the supporting shaft 14b is protruded on both sides of the central corner of the fan-shaped lower part. The shaft supporti...

Abstract

The rotation switch making a switching operation based on a rotational operation force of a rotation lever held by a housing and rotated for operation incorporates a tight-sealed switch making a switching operation of a contact part inside a tightly sealed case blocked from the outside air based on the rotational operation force of the rotation lever.

Description

technical field [0001] The present invention relates to, for example, a rotary switch used in a door switch of a refrigerator, and more particularly, to a rotary switch and a door switch for a refrigerator capable of ensuring reduced number of parts, miniaturization, and safety. Background technique [0002] Generally, a door switch assembled in a domestic refrigerator is provided near the door in the refrigerator, and it has the functions of turning on, turning off the light bulb illuminating the inside of the refrigerator, and turning on when the door of the refrigerator is opened and closed. Switch off the cooling motor switch function. [0003] However, in recent years, when making refrigerators, other types of refrigerants having the same cooling function have been used instead of Freon, which is one of the causes of global warming. For example, refrigerators using inexpensive hydrocarbons as refrigerants are being sold. [0004] However, because the hydrocarbon refri...
