Claim 17:
18. An ignition protected switch device for an explosive environment, the ignition protected switch device comprising: a housing defining a first enclosure and a second enclosure positioned on opposite sides of the housing, wherein the first and second enclosures are integrally formed with the housing; a line-side terminal and a load-side terminal coupled to the housing and being enclosed to provide ignition protected terminations in the explosive environment, wherein the line-side terminal is enclosed in the first enclosure and the load-side terminal is enclosed in the second enclosure; and a bus structure in the housing and including at least one solid state switching element operable in an arc-free manner to connect the load-side terminal to the line-side terminal and disconnect the load-side terminal from the line-side terminal; further comprising a controller configured to operate the at least one solid state switching element to maintain a surface temperature at or below a rated temperature, thereby precluding the housing from being an ignition source in the explosive environment.
