Pushbutton switch assembly

An electrical switch assembly comprising:

• chassis means for housing the electrical contacts of a switch, said chassis having a wall with at least one through opening therein;
• at least one switch actuator means mounted in said chassis wall opening, said switch actuator being attached to said chassis by flexible retaining means fixed to one of said chassis wall and said switch actuator means and having at least one flexible extending portion cooperating with a recess in the other of said chassis wall and said switch actuator means to form a hand-insertable snap-in subassembly, said flexible retaining means, besides attaching said switch actuator means to said chassis, also biasing said switch actuator means into a first predetermined position with respect to said chassis wall and permitting movement of said actuator means into a second predetermined position with respect to said wall while keeping said actuator means attached to said chassis;
• and
• electrical contact means mounted inside said chassis, said actuator means selectively altering the electrical characteristics produced by said contact means in response to said actuator means moving from said first to second positions,
• wherein one of said chassis wall and actuator means has at least one stop projection which cooperates with a mating stop surface on the other one of said chassis wall and actuator means to prevent movement of said actuator means beyond a predetermined limit position with respect to said wall while said actuator means is attached to said wall by said flexible retaining means.
