Electrical switch with a sealing member for use with an electrical device

Abstract

An electrical switch unit for use in controlling operation of an electrical device, the electrical switch unit including: an electrical switch unit housing for housing at least a pair of electrical switching contacts of the electrical switch unit, said electrical switch unit housing including a first housing member and a second housing member that are configured for attachment together at peripheral regions of the first and second housing members so as to cooperatively form an enclosed space for housing the pair of electrical switching contacts therein; an actuator member operably-connected with at least one of the pair of electrical switching contacts, the actuator being configured for movement relative inwardly and outwardly of an opening in the electrical switch unit housing so as to arrange the pair of electrical switching contacts into at least one of a closed configuration wherein power is able to be supplied from a power source to motor or other electrically-operable element of the electrical device via the pair of electrical switching contacts, and, an opened configuration wherein power is not able to be supplied from the power source to the motor or other electrically-operable element of the electrical device via the pair of electrical switching contacts; and an sealing element including an elastically-resilient polymeric material, said sealing element being configured for location between the first and second housing members and extending about the peripheral regions of the attached first and second housing members so as to occlude passage and ingress of particulates and water into the electrical switch unit housing.
