A push button switch device for use in applications, such as pedestrian signal control buttons and elevator buttons, that require identification of a direction associated with the switch device. The switch device has a pointer on the front end of the push button which points radially of the push button axis and is angularly adjustable about this axis relative to a fixed support mounting the switch device to change the pointing direction of the pointer relative to the support. Features are provided for the prevention of entry of water to a position in the control button structure wherein it could freeze and hinder operation.
