Abstract
An electrical switch may include a housing having a hollow inner cavity. Both mechanical and electrical components may be contained within the inner cavity. The components within inner cavity may be protected from contaminants entering the inner cavity by a seal adjacent to an opening of the housing leading from the inner cavity. The seal may allow movement of an actuator mechanism between various configurations relative to the seal, while continuing to prevent contaminants from entering the inner cavity.
