Claims
- 1. An electro-mechanical switch, comprising;
- (a) a hollow housing (1),
- (b) a rotor (5) centrally journalled within said housing,
- (c) a first cantilever spring contact (12) depressible by said rotor,
- (d) a second cantilever spring contact (11) depressible by said first spring contact,
- (e) plural, slight deformable rectilinear sides (7,7',9,9') upon said rotor dimensioned in relation to said hollow housing to exclusively force said rotor to occupy plural specific rotational positions, and
- (f) plural essentially symmetrical mutually-diverging projections (14,15) upon said rotor,
- one said projection (15) to force said spring contacts into mutual mechanical and electrical contact upon said rotor occupying one said specific rotational position, and
- another said projection (14) to force said spring contacts out of mutual mechanical and electrical contact upon said rotor occupying another said specific rotational position.
- 2. The switch of claim 1, in which;
- (a) said rotor is formed with hollow areas (16,17) adjacent to said rectilinear sides, and
- (b) said rectilinear sides are deformed by said hollow housing to force said rotor to occupy plural specific rotational positions.
- 3. The switch of claim 1, in which;
- (a) said first cantilever spring contact has a longitudinal ridge on the side adjacent to said second cantilever spring contact, and
- (b) said second cantilever spring contact has a transverse ridge on the side adjacent to said first cantilever spring contact,
- whereby the mutual mechanical and electrical contact between the contacts is a limited area.
- 4. The switch of claim 1, in which;
- (a) the coactive mechanical relationship between said projections and said cantilever spring contacts is such that said contacts engage with a single mechanical wiping action.
- 5. The switch of claim 1, in which;
- (a) said first and second cantilever spring contacts are oppositely disposed, one to the other, with the free ends thereof overlapping upon being pressed together by one of said essentially symmetrical mutually-diverging projections.
- 6. The switch of claim 1, in which;
- (a) the top of said rotor is concave upward, with a central depression and raised portions at each extremity.
- 7. The switch of claim 1, in which;
- (a) the top of said rotor is concave downward, and
- (b) said rotor is disposed within said housing to be completely within said housing regardless of the rotational position of said rotor.
- 8. The switch of claim 1, in which;
- (a) said first and second cantilever spring contacts (12',11') are each of equal length and flat at the adjacent extremities thereof.
- 9. The switch of claim 1, in which;
- (a) said first cantilever spring contact (12') overlays said second cantilever spring contact (11').
- 10. The switch of claim 1, in which;
- (a) said first cantilever spring contact (12') can be on either side of the housing.
- 11. The switch of claim 1, which includes;
- (a) plural housing sections (10,10'), each having a rotor (25,25'), and
- (b) first (12') and second (11') cantilever spring contacts.
- 12. The switch of claim 1, in which;
- (a) there are plural sets of first and second cantilever spring contacts in said housing, and
- (b) said rotor bears upon said plural sets of contacts.
- 13. The switch of claim 12, in which;
- (a) said first cantilever springs (12') can be on either side of the housing.
