Abstract (en)
[origin: ES8104634A1] A low voltage contactor switch has three simultaneously actuated pairs of contacts each of which consists of a movable and a fixed contact, with contacting occurring in a single evacuated area within a vacuum tube for minimizing oxidation of the contact surfaces and thereby increasing contact life. The contacts are connected to terminals which extend through walls of the vacuum tube in air tight fashion with actuation of the movable contacts being undertaken with the use of an air-sealed bellows. Each contact pair may be individually isolated by a cylinder within the evacuated area surrounding each contact pair as well as by a Y-shaped plate dividing the evacuated area into three chambers.
