【Breach】 , 【infraction】 , 【violation】 , transgression,  【trespass】 , 【infringement】 , 【contravention】 are comparable when denoting the act or the offense of one who fails to keep the law or to do what the law, one′s duty, or an obligation requires.

【Breach】 occurs rarely by itself except in phrases such as "a law more honored in the 【breach】 than in the observance."

The word is usually followed by o/and a noun or pronoun which indicates the thing which is broken or not kept.

【Infraction】 is now more often used than 【breach】  (except in certain time-honored idioms) for a breaking of a law or obligation.

【Violation】 adds to 【breach】 and  【infraction】 the implication of flagrant disregard of the law or of the rights of others and often suggests the exercise of force or violence; thus, the 【violation】 of a treaty suggests positive, often aggressive and injurious action, while its  【infraction】 may imply a mere failure strictly to adhere to its terms.

【Transgression 】 is applied to any act that goes beyond the limits prescribed by a law, rule, or order; often the term is used specifically of an 【infraction】 of the moral law or of one of the commandments.

【Trespass】 also implies an overstepping of prescribed bounds, but it carries in addition a strong implication of encroachment upon the rights, the comfort, or the property of others. In Scriptural and religious use a 【trespass】  is particularly an offense against God or one′s neighbor.

In law a 【trespass】  is an unlawful act, involving some degree of force or violence, committed against the person, the property, or the rights of another.

【Infringement】 is sometimes used as though it were identical in meaning with 【infraction】 .

More often it implies 【trespass】  rather than 【violation】 and therefore is the idiomatic term when 【trespass】 involving an encroachment upon a legally protected right or privilege is at issue; thus, the unauthorized manufacture of something which has been patented constitutes an 【infringement】 (rather than an 【infraction】  or 【violation】 ) of a patent.

【Contravention】 applies specifically to a going contrary to the intent of the law or to an act in defiance of what is regarded as right, lawful, or obligatory.
