Abstract
The present invention relates to a detector for theft prevention used in contact with a commodity or the like exhibited in a shop.
Conventionally, an operated portion for contacting a commodity or the like is pivotable only in one direction from a projected position. The commodity or the like cannot be moved in directions requiring the operated portion to pivot in directions other than that direction. A forcible movement would damage the operated portion.
In a detector for theft prevention of this invention, a switch (3) provided for a box (2) thereof has a pivotable operated portion (3a) biased to return to a position projecting from a surface (2c, 2d) contacting an object of theft prevention (E). The operated portion (3a) is pivotable in a plurality of directions including at least two opposite directions (e1, e2). The detector for theft prevention is properly operable for movements in varied directions of the object of theft prevention (E).
