Abstract
A contactless control switch (20) for a vehicle for actuating a system between an open and a first closed circuit position is disclosed. The switch includes a housing (22) and a pivot assembly (24) disposed within the housing. The switch also includes a switch actuator (26) having first and second ends. The switch actuator is coupled to the pivot assembly for producing pivoting motion of the switch actuator in response to a force (84) applied to the switch actuator. The switch also includes first and second proximity sensors (80a and 80b) and a first magnet (70). The proximity sensors are disposed within the housing and the first magnet is fastened to the switch actuator second end. The first magnet is adapted to be selectively displaced into and out of close proximity with one of the proximity sensors when the force is applied to the switch actuator. The switch (20) also includes a biasing member (52a and 52b) disposed between the switch actuator and the pivot assembly for biasing the switch actuator into an open circuit position.
