Limit Switches

Rugged Joyce limit switches allow you to set precise travel limits and stops on Joyce jacks and actuators. They are also ideal in any applicaiton where rotary motion of a machine component can be used to indicate linear motion of another part.

LS8 Limit Switches
LS8 limit switches are best suited for general purpose applications requiring up to four switch contacts for operating motors, lights and other accessories. The LS8 is available in two models; the LS8 402 (two switch unit) and the LS8 404 (four switch unit). Both LS8 models offer a NEMA 4 rated enclosure that is rated for dust, rain and hose directed water. Limit switch adjustment is achieved by simply loosening a cam detent screw and rotating the switch trip cam to the desired position.

LS9 Limit Switches
LS9 limit switches are recommended for general purpose applications that require up to seven switches. Similar to the LS8 model, the LS9 offers the same high quality NEMA 4 rated enclosure. Five models are available, from the two switch LS9 502 to the seven switch LS9 507. Limit switch adjustment is accomplished with screwdriver adjustment of a self-locking worm gear connected to the switch cam. Single pole double throw (S.P.D.T.) switches are standard and double pole double throw (D.P.D.T.) are optional.

ELS Electronic Limit Switches
The Joyce Electronic Limit Switch (ELS) combines the precision of screw jack positioning in .001" increments with the convenience of a backlit LCD readout that displays both position and travel speed. Three models of ELS switches feature two, four or six user programmable stops, a line text or two-color display, keypad, up/down pilot lights, and are available with an RS-232 serial interface.
