1. Pressure operated switch with a housing (2; 18) on which an elastic contact arm (3; 20, 21) is fixed and whose movable part projects into the housing and comprises a contact (5) co-operating with a contact (5, 8) integral with the housing, the movable part between the fixing zone and the contacts (5, 6, 8) abutting at one side against an abutment (15, 16; 22, 23) adjustable from the outside of the housing and being acted upon from the other side, at least between the abutment and the contacts, by a pressure pad (10; 24, 25), characterised in that a guide (13) is provided which is fast with the housing and which extends along the movable part of the contact arm (3; 20, 21), and that the abutment (15, 16; 22, 23) is mounted to be displaceable in the guide (13) between the fixing zone and the contacts, without modifying the spacing between the contacts (5, 6, 8) when the abutment (15, 16; 22, 23) is displaced. |
