Abstract

Disclosed is a direct current switch which comprises, in a housing, a slidable actuator, one stationary contact and one pseudo stationary contact both fixed to the housing, a seesaw-like plate having one movable contact and one pseudo movable contact fixed to its opposite ends, and a swingable pusher operatively connected to the actuator to apply a pushing force to the seesaw-like plate all the time. The seesaw-like plate is supported by a fulcrum support to be balanced in the middle. The seesaw-like plate has an engagement piece fixed thereto in the vicinity of the movable contact, and the actuator has a resilient catch-and-hold piece fixed thereto on the movable contact's side. While the actuator is on the way to the end, the resilient catch-and-hold piece can catch and hold the engagement piece until the pusher makes the seesaw-like plate to be inclined toward the stationary contact, making the resilient catch-and-hold piece forcedly release the engagement piece, allowing the movable contact to quickly abut on the stationary contact.
