A roll for rotating a movable contact of a rotary switch, the roll comprising:
- a first slot extending along a diameter of the roll and open from a top side of the roll for receiving the movable contact for contacting with a stationary contact of the rotary switch;
- a second slot arranged perpendicular to the first slot for receiving teeth of an upper roll to be mounted together with the roll;
- and
- four teeth on the top side of the roll defining the first and second slots,
- wherein the four teeth include a first tooth, a second tooth, a third tooth and fourth tooth;
- the first slot is defined by a space formed between the first and second teeth and a space between the third and fourth teeth;
- and
- the second slot is defined by a space between the first and third teeth and a space between the second and fourth teeth such that the first and second slots are each on the same end of the roll.
A switch according to 13, wherein the mechanism body and the intermediate body comprise a round hole, and the roll includes a collar for preventing the roll falling through the hole when mounted to the body from the top side.
A switch according to 10, wherein the mechanism body and the intermediate body comprise a round hole, and the roll includes a collar for preventing the roll falling through the hole when mounted to the body from the top side.
A method of mounting a switch, comprising:
- mounting a movable contact to a first slot of a first roll, the first slot extending along a diameter of the first roll and open from a top side of the first roll for receiving the movable contact for contacting with a stationary contact of a rotary switch, the first roll having a second slot arranged perpendicular to the first slot;
- and
- mounting a second roll to the first roll such that a pair of teeth on a bottom of the second roll set to the first slot of the first roll above the movable contact, and a pair of teeth on the bottom of the second roll set to the second slot of the first roll,
- wherein the first roll comprises four teeth on the top side of the first roll defining the first and second slots,
- wherein the four teeth include a first tooth, a second tooth, a third tooth and fourth tooth,
- wherein the first slot is defined by a space formed between the first and second teeth and a space between the third and fourth teeth, and
- wherein the second slot is defined by a space between the first and third teeth and a space between the second and fourth teeth such that the first and second slots are each on the same end of the roll.
