Abstract
To locate an electric switch relative to a fixed part a bush having a plurality of mating members and a projection in an opening through the bush is positioned in the fixed part. The switch is positioned at one end of a switch carrier having an elongate portion which is also provided with mating members and a projection. The elongate portion is introduced axially into the opening and then rotated to cause the mating members to engage and axially locate the elongate portion in the opening. The projections take up relative positions in which they only permit rotation in the opposite direction to disengage the mating members when sufficient force is applied to deform one or both of the projections.
Claims10
The combination of
- a body having
- an opening therein,
- a plurality of members extending around part of the side wall of the opening, said members being arranged side-by-side in the direction parallel to the depth of the opening, and
- a projection projecting from the side wall into the opening and
- a switch carrier having
- an elongate portion,
- a plurality of members extending around part of the side wall of the elongate portion, said members being arranged side-by-side in the direction parallel to the length of the elongate portion and
- a projection projecting outwardly from the side wall of the elongate portion,
- the opening in the body and the elongate portion of the switch carrier being such that the elongate portion is insertable in the direction of its length into the opening and by causing limited relative rotation between the elongate portion of the carrier and the body in a first direction members on the body and members on the carrier mate together to axially locate the carrier in the body and the projections being such that said relative rotation in the first direction cause them to take up relative positions which prevent relative rotation between the body and the elongate portion in the opposite direction unless the applied force to bring about relative rotation in said opposite direction is sufficient to deform one or both of the projections.
