The vacuum switch includes a ceramic and metal housing having a metal body portion with a generally T-shaped cross-section forming three ends. Ceramic insulators are brazed on each of the three ends with the insulators being closed by metal end members. A first end receives a stationary conductor with the opposite second end reciprocably receiving an actuator member. A second stationary conductor is disposed at the third end transversely of the axis of the first stationary conductor. The first conductor includes a stationary switch contact disposed on its terminal end. A moveable switch contact is disposed on the terminal end of the actuator member. The second stationary conductor includes a flexible cantilever beam extending therefrom and received within an aperture in the actuator member for the moveable switch contact. The flexible cantilever beam flexes between a closed circuit position when said moveable switch contact engages the stationary switch contact and an open circuit position when the moveable switch contact is out of engagement with the stationary switch contact.
