The B-B section of Fig. 1 derived from Fig. 7 is provided with the cover 70; the provided contact flash unit to contact flashes 31-34; the second contact bleach unit to the contact bleach 31'-34 '; or, the 31-33 $ contact springs 111-112, 141-142 of the contact contact spring unit; eamt contact springs 111'-112 ', 141'-142' in the second contact spring assembly.

Of the 1 following. 10 full-length C-C from the following. 7 dispenses the casing 70; the contact contact unit at the etoma 10, the contact spring 11, booked the terminal end 113 and contact terminal 1111; the second contact spring unit with etomaan 10 ', contact spring 11', booked tapered end 113 'and contact pad 1111'; the contact bleaching unit at the etoma 30, the contact bleach 32, the contact fabric 321, and the booked end portion 322; the second contact bleaching unit at the floor 30 ', the contact bleaching 32', the contacting fabric 321 'and the booked end portion 322'; eaat elutllgen kamarein 71. Donna Occupy or position that the contact is the elut nelien contact times 321 ooh 1111 ooh or between the contact pieces 321 'ooh 1111'.

Soa fraagär by the following. 9 and 10, the movable contact springs 11, 11'-14 »14 'end into one more bounded by the two contact bleachers at the top and bottom of the spacer.

The chamber 71 stored in the auxiliary unit 30-33 is rotatable a total angle greater than the angle so required for the intended contact function lanes between the contact blades 31-34 »31'-34 'and contact springs 11-14» 11'-14' and this without significant increase. of required maneuvering force on the cam or in the point of contact on the contact spring.

The contact springs' and the contact ends of the contact springs can be acoustically attached to a circuit board. In the valid space, four separate breaks and four separate electrical outputs, or similar oblique ports on the circuit board, give rise to breaks, electrical outputs, switches and / or contacts in accordance with the desired realization.
