This invention relates to a snap action electrical switch.
A snap action switch is a switch in which the speed of the contacts during actuation of the switch is relatively independent of the speed of the actuating mechanism. In switches of this type, it is desirable to minimize the opening and closing times of the switch, to prevent damage to the electrical equipment which the switch controls. It is also desirable in switches of this type to minimize the size of the switch, since these types of switches are often used in aircraft or other installations in which space constraints severely limit the maximum size of the switching mechanism. It is also desirable to provide a switch with reversible contact arrangements, so that the same switch, with minor modifications, may be used as a two-circuit switch; as a single pole, double-throw switch; or as a single pole normally opened or normally closed switch.
