Abstract
In this device, a mechanism for receiving an input mechanical command and for actuating first and second switches comprises a lever having a first side arm tiltable about a swiveling axis of said lever and a second side arm tiltable about the same swiveling axis. The first side arm and the second side arm are respectively arranged on a first side and a second side opposite relative to said swiveling axis. The first side arm is an operating arm for operating the first switch. The second side arm is an operating arm for operating the second switch.
Claims16
A mechanically operated electrical switch device, comprising:
- a first electric switch actionable between open and closed states,
- a second electric switch actionable between open and closed states,
- a shaft rotatable about its longitudinal axis,
- a first side arm extending substantially radially from said shaft, for operating the first switch,
- a second side arm extending substantially radially from said shaft, for operating the second switch,
- the first side arm and the second side arm, respectively, extending from a first side and an opposite second side of said shaft,
- the first switch being on the first side of said axis, the second switch being on the second side of said axis,
- and each of the first and second switches comprises:
- a fixed contact,
- a mobile contact mobile between an open state in which this mobile contact is at a distance from the fixed contact, and a closed state in which the mobile contact and the fixed contact meet to thereby establish an electrical connection, and
- a controllable support for the mobile contact, which support is a conductor for electrically connecting the mobile contact to an electric circuit and is controllable between a position in which said mobile contact is in the open state and a position in which said mobile contact is in the closed state,
- the first side arm being positioned for operating the controllable support of the first switch, and the second side arm being positioned for operating the controllable support of the second switch.

A mechanically operated electrical switch device,
- a first electric switch actionable between open and closed states,
- a second electric switch actionable between open and closed states,
- a shaft rotatable about its longitudinal axis,
- a first side arm extending substantially radially from said shaft, for operating the first switch,
- a second side arm extending substantially radially from said shaft, for operating the second switch,
- the first side arm and the second side arm, respectively, extending from a first side and an opposite second side of said shaft,
- the first switch being on the first side of said axis, the second switch being on the second side of said axis,
- and each of the first and second switches comprises a finger for movement in a direction in a plane which is substantially parallel to a plane which includes the axis of the shaft, for thereby actuating said switches between their open and closed states, the first side arm is positioned for contacting the finger of the first switch and displacing the finger of the first switch when the shaft is rotated in a first rotary direction thereby actuating the first switch, and
- the second side arm is positioned for contacting the finger of the second switch when the shaft is rotated in a second opposite rotary direction thereby actuating the second switch, and wherein each switch additionally comprises:
- a fixed contact,
- a mobile contact located on the finger for movement between an open state in which the mobile contact is at a distance from the fixed contact, and a closed state in which the mobile contact and the fixed contact meet to thereby establish an electrical connection, and
- in at least the first switch, the finger bearing the mobile contact is a conductor for electrically connecting the mobile contact to an electric circuit.
