  • Electrical rotary push switch
    Patent number: 5939686
    Abstract: An electrical rotary push switch includes a housing having a longitudinal axis and an actuating element mounted around the housing. The actuating element is rotatable around and longitudinally movable about the housing to define switching positions. A functional element is mounted around the housing and is coupled to the actuating element to rotate as the actuating element rotates. The functional element remains fixed in position as the actuating element longitudinally moves. A first electrical contact part is slidably held to the housing to be longitudinally movable along the housing longitudinal axis. The first contact part is coupled to the functional element such that the first contact part longitudinally moves as the actuating element rotates and remains fixed in position as the actuating element longitudinally moves. A second electrical contact part is slidably held to the housing to be longitudinally movable along the housing longitudinal axis.
