ABSTRACT:
A locking switch for electrical automobile systems connects and disconnects an automobile battery to the starter. The locking switch has two normally separated contact plates, one connected to a cable from the battery and the other being connected to a cable from the starter. A lock cam is mounted at the end of a cylinder lock, which is key-actuated. The lock cam carries a spring-loaded copper ball that rotates with the lock cam upon actuation by the key. The cam and ball can be moved from an open position on one stationary contact to a closed position, whereby the ball provides electrical contact between the two stationary contacts, thus completing the electrical circuit between the battery and the starter. Each stationary contact is provided with a semispherical indentation in which the ball is received in the open position, thereby providing a substantial contact area between the ball and each of the two stationary contacts. The stationary contacts are received in a circuit insulator, which positions and spaces them from one another. A divider portion of the circuit insulator is notched for receipt of the copper ball in the operative position, such that the divider portion together with the indentations in the two stationary contacts form a substantially continuous semispherical indentation for receipt of the copper ball.
