Switch for disconnecting an electrical circuit

A switch comprising:

• a first cam engageable by a user and axially rotatable around a first axis by an operating angle between an on position and an off position;
• a second cam contacting the first cam, wherein:
• rotation of the first cam causes rotation of the second cam around the first axis, and
• the second cam comprises an axial cam portion and a transverse cam portion, the transverse cam portion comprising a protrusion extending along a direction perpendicular to the first axis and two detents arranged symmetrically either side of the protrusion, wherein the two detents are arranged at an oblique angle, θ, with respect to each other;
• and
• one or more biasing members configured to exert a force on the transverse cam portion of the second cam,
• wherein the axial cam portion is configured, upon rotation of the second cam by the first cam and/or a rotation of the second cam in response to the force exerted by the one or more biasing members, to cause opening and closing of a current conduction path through the switch.
