Abstract
An exemplary electric switch mounting arrangement includes a housing and a stationary contact to be mounted to an aperture in a wall of the housing. The arrangement having a compensation component within the interior area of the aperture for allowing stationary contacts of two different sizes to be mounted to the aperture, which compensation component includes one or more projections formed on the housing or the stationary contact and/or one or more recesses formed on the housing or stationary contact for receiving the one or more projections.
Claims14
An electric switch mounting arrangement comprising:
- a housing;
- and
- a stationary contact to be mounted to an aperture in a wall of the housing,
- wherein the housing includes a first projection within an interior area of the aperture for allowing stationary contacts of two different thicknesses to be mounted to the aperture such that when a stationary contact of a greater thickness is mounted to the aperture, a recess in the greater thickness of the stationary contact of the greater thickness is arranged to receive the first projection of the housing, and when the stationary contact of a smaller thickness is mounted to the aperture, the stationary contact is arranged to lie on the first projection of the housing.
A method of mounting a stationary contact to a switch housing, the housing having an aperture in a wall of the housing for receiving a stationary contact, wherein the housing includes a projection in the aperture, the method comprising:
- mounting a first stationary contact or a second stationary contact to the aperture, wherein the first stationary contact has greater thickness than the second stationary contact,
- when mounted to the aperture, the first stationary contact has a recess in the greater thickness thereof for receiving the projection of the aperture, and
- when mounted to the aperture, the second stationary contact is arranged to lie on the projection of the aperture.
