This invention discloses a multi-contact parallel-connected snap-action electromagnetic relay, comprising a snap-action armature, a moving spring portion, and a stationary spring portion; the stationary spring portion includes two stationary spring plates for realizing current inflow and outflow; one end of the moving spring portion is connected to the armature; at least three sets of contacts are provided between the moving spring portion and the two stationary spring plates to form at least three-contact parallel circuits. This invention can realize more than three-contact parallel circuits, which can reduce contact resistance, reduce temperature rise, and reduce total Holm force, thereby preventing relay failure.
