The apparatus of claim 1 wherein said cover (12) is designed to carry out a pivoting movement between an open position and a closed position and a translational movement between said closed position and a locked position, both with respect to said contact element support.
Claim 10
Dependent Claim
51 words
The apparatus of claim 1 wherein the cover is a stamped and bent part made of sheet metal, and said contacting and connecting means is a leaf spring formed by a side wall of said cover being bent around by 180° to extend parallel to the top surface of the cover.
Claim 11
Dependent Claim
56 words
The apparatus of claim 9 wherein a shielding effect is generated by the closed metal cover (12) and wherein the connection for shielding purposes between said cover and ground by means of said switch contact elements occurs preferably within the outline of the card, said spring being pressed against at least one of said switching contacts.
Claim 12
Dependent Claim
34 words
The apparatus of claim 8 wherein the cover (12) and the contact element support are provided at one end with linkage or connecting means (61, 62) adapted to provide said pivotal and translational movements.
Claim 13
Dependent Claim
22 words
The apparatus of claim 11 wherein said connecting means comprises first stationary and second moveable pivot bearing means (41, 141; 42, 142).
Claim 14
Dependent Claim
28 words
The apparatus of claim 12 wherein abutment means (65, 75) are provided such that the cover (12) cannot make translational movements if it is in an open condition.
Claim 15
Dependent Claim
24 words
