Abstract:
A direct current switch comprising a housing, an actuator slidably fixed to the housing, a support fixed to the housing, one stationary contact and one pseudo stationary contact both fixed to the housing, the stationary and pseudo stationary contacts being arranged symmetrically with respect to the support, a seesaw-like plate having one movable contact and one pseudo movable contact fixed to its opposite ends, the seesaw-like plate being supported by the support to be balanced in the middle, and a swingable pusher operatively connected to the actuator to apply a pushing force to the seesaw-like plate all the time, wherein the seesaw-like plate has an engagement piece fixed thereto in the vicinity of the movable contact, and that the actuator has a resilient catch-and-hold piece fixed thereto on the movable contact's side, whereby while the actuator is on the way to the end, the resilient catch-and-hold piece may 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.
