Abstract (en)

A push button switch comprises an electrical contact module (1), an enlarged halo (4) to accommodate a switch actuator (3) and a legend plate (4.7), and a halo adapter (2) interfacing the halo (4) with the electrical contact module (1), whereby halo (4) and halo adapter (2) define a housing for the switch actuator (3). Actuating legs (3.2) of the switch actuator (3) engage a spring biased contact carrier (1.3) of the electrical contact module (1) and the contact carrier (1.3) thus pushes the switch actuator (3) against a first projection (4.2) of the halo (4). An actuating force applied to a lens (3.5) of a lens cap (3.4) overcomes the bias of the contact carrier (1.3) causing the switch actuator (3) to travel inside the switch actuator housing. The switch actuator (3) comes to rest as soon as a base portion (3.1) reaches a wall (2.3) of the halo adapter (2). <IMAGE>
