Bulletin 802T Oiltight Limit Switches provide heavy-duty pilot ratings, small size, a high degree of versatility and a rugged NEMA Type 13 oiltight construction. Plug-in and non plug-in styles are available. Plug-in limit switches have a head and switch body that can be replaced while leaving the wiring chamber base in place. This reduces your down time by eliminating the need for rewiring upon switch replacement.
