The main use of the 3ZNA key switch is in electrically powered vehicles where the supply voltage is typically switched on and off. When the key is turned to the ON position, the three 6.3 x 0.8 flat-blade terminals on the base are connected. The key can only be removed in the OFF position. The key bow can come in different colours and with customised logos.
