Abstract
The invention includes a switch designed for use in adverse conditions such as for use with physically challenged persons. The switch can include a housing comprising top and bottom housings. The top and bottom housing each have a mating surface which guide the top and bottom housing during activation of the switch while permitting an activation force applied from various directions to activate an electrical switch located within the housing. The switch can include a flange type seal member for resisting entrance of contaminants into the housing and can include a ring member for attaching the switch to a user's body for easy manipulation of the switch. In addition, the switch is designed to be quickly and easily fit together during assembly and therefore easily manufactured.
